Introduction
INTRODUCTION
TIBCO Spotfire S+ provides a plug-in, or customization, of the
Eclipse Integrated Development Environment (IDE) called the
Spotfire S+ Workbench. You can use the Spotfire S+ Workbench, the
basic Eclipse IDE features, and other third-party plug-ins for many
tasks, including:
•
Manage your project files and tasks.
•
Edit your code.
•
Run Spotfire S+ commands.
•
Examine Spotfire S+ objects.
•
Debug your code.
•
Track resource use, functions, variables, and expressions.
•
Troubleshoot problems with Spotfire S+ code.
•
Provide source control for shared project files.
The Spotfire S+ Workbench is a stand-alone application that runs the
S-PLUS engine. When you run the Spotfire S+ Workbench, you do
not need to run any other version of Spotfire S+ (for example, the
console or traditional Windows or Java GUI).
Caution
If you run two or more simultaneous sessions of Spotfire S+ (including one or more in the
Spotfire S+ Workbench), take care to use different working directories. To use the same working
directory for multiple sessions can cause conflicts, and possibly even data corruption.
This chapter introduces the Spotfire S+ Workbench and provides
important conceptual information and definitions of terms you need
to know to use the Spotfire S+ Workbench most effectively.
•
Chapter 2 provides reference for the Spotfire S+ perspective.
•
Chapter 3 provides reference for the Debug perspective.
•
Chapter 4 provides tasks for learning to use the Spotfire S+
Workbench.

Chapter 1 The TIBCO Spotfire S+ Workbench
TERMS AND CONCEPTS
Before you start using the Spotfire S+ Workbench, you should
understand key terms and concepts that vary from the traditional
Spotfire S+ for Windows GUI and Spotfire S+ for UNIX Java GUI.
Note
If you are using the Eclipse IDE on a UNIX platform from a Windows machine using a
Windows X-server software package, you might notice that Eclipse runs slowly, similar to the
Spotfire S+ Java GUI. See the Release Notes for more information and recommendations for
improving UI performance.
Note
Eclipse version 3.2 or later does not support SPARC/Motif for Solaris. If you are using a version
of Solaris prior to version 10, you must install the GTK (version 2.2.4 or greater) library. For
more information about finding this library, see http://www.sun.com/software/solaris/. (This
library is included in Solaris 10.)
Table 1.1: Important terms and concepts.
Term
Definition
Perspective
Defines the preferences, settings, and views for working with
Eclipse projects.
• The Spotfire S+ perspective is conceptually equivalent to
the traditional Spotfire S+ Windows GUI or UNIX Java
GUI. Use the Spotfire S+ perspective as the primary
perspective for interactive Spotfire S+ command line use.
For an example of changing the perspective, see the
section Customized Perspective Views on page 148.
• The Debug perspective provides an integrated debugging
and profiling environment, with customized views, menu
options, and behavior. For more information about using
the Debug perspective, see Chapter 3, TIBCO Spotfire S+
Workbench Debug Perspective.

Terms and Concepts
Table 1.1: Important terms and concepts. (Continued)
Term
Definition
Workspace
A physical directory on your machine that manages Spotfire
S+ Workbench resources such as projects and other options.
On your machine's hard drive, the workspace directory
contains a single Spotfire S+ .Data database and the Eclipse
.metadata database. (You should never touch these
resources.) This design is different from the association you
notice when you work in Spotfire S+ in other environments.
When you start the Spotfire S+ Workbench, you are
prompted to create or identify the workspace. See the section
The Spotfire S+ Workspace on page 12.
Project
A resource containing text files, scripts, and associated files.
The Spotfire S+ Workbench project is used for build and
version management, sharing, and resource management.
Before you begin working with any files in the Spotfire S+
Workbench, create a project. You can create a new project
by:
•
Specifying a project name and allowing Eclipse to
locate the project in the workspace directory, and
then selecting an existing directory containing
project files at an alternate location (that is, work
with the files at the specified location).
•
Specifying a project name and selecting an existing
directory containing project files.
Another important concept is that of the working project. Set a
project as the working project, which changes the working
directory to the project’s directory in your workspace and
stores data objects in the project’s .Data database. See the
section Setting the Working Project on page 151 for more
information.
Important: If you select an existing Spotfire S+ project
directory for your Workbench project, you must set that
project to be the working project to write data objects to its
.Data directory. See the section Working Projects and
Databases on page 151 for a detailed discussion. See the
section Quick Start on page 127.

View
A perspective’s integrated window, containing menus,
options, and commands, that display specific parts of your
data and projects and provide tools for data manipulation.
For descriptions of the Spotfire S+ perspective views, see the
section Spotfire S+ Perspective Views on page 68. For
descriptions of the Debug perspective views, see the section
Debug view on page 100. For practice exercises working with
views, see Chapter 4, TIBCO Spotfire S+ Workbench Tasks.
Editor
An integrated code/text editor that includes support for
syntax coloring, text formatting, and integration with the
other views. Analogous to the Script Editor in the traditional
Spotfire S+ GUI. For more information, see the section
Spotfire S+ Workbench Script Editor on page 57. To practice
using the Script Editor, see the section Editing Code in the
Script Editor on page 157.

Chapter 1 The TIBCO Spotfire S+ Workbench
STARTING THE SPOTFIRE S+ WORKBENCH
The Spotfire S+ Workbench user interface is the same in both
Microsoft Windows and UNIX platforms.
From Microsoft
Windows
In Microsoft Windows, click the Start menu All Programs
TIBCO TIBCO Spotfire S+ 8.2 TIBCO Spotfire S+
Workbench.
Setting
Environment
Variables
When you start the Spotfire S+ Workbench from the Windows Start
menu, it uses a shortcut that starts a Java virtual machine (-vm)
immediately. The Workbench supports a Java system variable,
splus.environment.vars, that can pass environment variables to the
engine for startup consumption. For example, you can set your
Spotfire S+ Workbench environment to start without printing
copyright and version infromation by setting the environment
variable S_SILENT_STARTUP=<any value>.
To use the Java system variable, create a shortcut or a .bat file that
contains the following instructions:
"SHOME\eclipse\eclipse.exe"
-vm "SHOME\java\jre\bin\javaw.exe" -vmargs
-Dsplus.shome="SHOME"
(Where SHOME is your Spotfire S+ installation location.
Note that this is the default Windows XP shortcut, as it appears in the
Spotfire S+ Workbench Properties dialog (see Figure 1.3).
To add an environment argument in Windows
1. Click Start Program Files TIBCO TIBCO Spotfire S+ 8.2.
2. Right-click Spotfire S+ Workbench.
3. In the Spotfire S+ Workbench Properties dialog, type the
following after -vmargs:
4. -Dsplus.environment.vars=”VAR1=arg1, VAR2=arg2”
where VAR is the variable to set and arg is the argument you
are setting. For example:
10
Starting the Spotfire S+ Workbench
-Dsplus.environment.vars=”S_LICMGRSN=WTP10987654321,
S_SILENT_STARTUP=X”
Note
The Windows startup shortcut is defined to run a command with the option to set memory heap
size: -Xmx400m.
"SHOME\eclipse\eclipse.exe" -vm "SHOME\java\jre\bin\javaw.exe"
-vmargs -Dsplus.shome="SHOME\eclipse\eclipse.exe -Xmx400m”
You can override this setting and increase the memory heap size by appending a different setting
at the end of the shortcut. (For example, change -Xmx400m to -Xmx600m at the end of the
command to set the memory heap size to 600mb.) See Figure 1.3 for an example.
Figure 1.3: Spotfire S+ Workbench Properties dialog.
From Unix
In UNIX, at the command prompt, type
Splus -w
or type
Splus -workbench
11
Chapter 1 The TIBCO Spotfire S+ Workbench
Setting
Environment
Variables
Certain required environment variables are set to work with UNIX
and Linux as part of the Spotfire S+ Workbench startup script. To add
other environment variables, set them using env. For example, you
can start the Spotfire S+ Workbench with a particular license and to
start displaying no copyright and version information by using the
following:
env S_LICMGRSN=WTP10987654321 S_SILENT_STARTUP=X
Splus -w
(To set multiple environment variables, separate them with spaces. )
To extend the Java maximum memory heap size to 600MB, set the
environment variable JAVA_OPTIONS to -Xmx600m. For example:
env JAVA_OPTIONS="-Xmx600m" Splus -w
The Spotfire
S+ Workspace
When you launch the Spotfire S+ Workbench, you see the
Workspace Launcher dialog. You must indicate the location of the
workspace.
Figure 1.4: The Workspace Launcher dialog.
The Spotfire S+ workspace is the directory where the Spotfire S+
workspace .Data and Eclipse .metadata databases are stored. (You
should never touch these files.) Optionally, the workspace directory
can also store your project directories. The Spotfire S+ workspace is
the default directory specified for the project's directory in the New
Project wizard. See the section Spotfire S+ New Project Wizard
on page 31 for more information. (For instruction on creating a
workspace, see the section Setting the Workspace on page 126.)
12
Starting the Spotfire S+ Workbench
Important
In the Spotfire S+ Workbench, you have two options for storing data
objects:
•
Using the Spotfire S+ Workbench model, where the Spotfire
S+ workspace contains a .Data directory, not individual
projects. The .Data directory can store objects for projects to
share in the workspace.
•
Using the familiar Spotfire S+ model, the working Spotfire S+
project stores its data objects to its .Data directory and replaces
the first entry in the Search Path with the project's location.
It is also the location to which relative paths are resolved.
Working projects are marked by an arrow icon, and by the
cue (working) in the navigator:
Figure 1.5: The working project.
For more information about setting the Spotfire S+ working project,
see the section Setting the Working Project on page 151.
Figure 1.6: Workspace directory (in Windows) showing .Data directory,
.metadata directory, and project directories.
Notes
When you work with Spotfire S+ Workbench projects, avoid nesting projects (that is, create one
project in a subdirectory of another project).
To avoid conflicts, never work on Spotfire S+ files in the Spotfire S+ Workbench and another
Spotfire S+ interface at the same time.

INTRODUCTION
TIBCO Spotfire S+ Workbench perspectives define the appearance
and behavior of the Spotfire S+ Workbench Eclipse plug-in,
including the Spotfire S+ Script Editor, views, menus, and toolbars.
The Spotfire S+ perspective combines Spotfire S+ Workbench views
and options so you can accomplish specific types of tasks and work
with specific types of resources.
•
For more information about the Spotfire S+ Debugger
perspective options and views, see Chapter 3.
•
For practice instruction using the features in the Spotfire S+
perspective, as well as the Spotfire S+ Workbench and Debug
perspective, see Chapter 4, TIBCO Spotfire S+ Workbench
Tasks.
Note
You can change a perspective to suit your development style by moving, hiding, or closing
views. For more information about customizing the views within the perspective, see the section

Both the Spotfire S+ perspective and the Debug perspective also
display the default Eclipse Navigator view, which displays project
directories and all files associated with each project. The Navigator
view and other Eclipse IDE views are described in the Eclipse
Workbench User Guide.
Customizing
the Spotfire
S+ Perspective
Views
The default Spotfire S+ perspective settings control the views that
open by default in preset locations; however, you can customize the
view appearance, and then save the resulting perspective. See the
section Customized Perspective Views on page 148 for more
information.
The following sections describe only the views that appear by default
in only the Spotfire S+ perspective.
History
The History is similar to the Commands History dialog in Spotfire
S+ for Windows. The History is a scrollable list of commands that
have previously been run in the Console. (Commands that you run
by clicking Run Spotfire S+ Code or pressing F9 do not appear in
the History. See the section Output on page 56.)
69
Chapter 2 The TIBCO Spotfire S+ Perspective
•
When you select a command in the History, the pending text
in the Console changes to the selected text. You can then
press ENTER, or you can double-click the text in the History
to execute the command. You can select only one line at a
time in the History.
•
When you scroll up or down through previously-run
commands in the Console, the corresponding command is
highlighted in the History.
Note
In Windows, Spotfire S+ uses the key F10 to run a selected command. The Spotfire S+
Workbench uses the key F9 to run a selected command in all platforms.
Figure 2.2: Spotfire S+ Workbench History
History control and right-click menus
You can use the History control menu (click
70
) to:
•
Select input displayed in the History and copy it to the
Console.
•
Clear the History.
Spotfire S+ Perspective Views
Note
In the Preferences dialog, you can set the option to persist entries in the History between
sessions. For more information about this option, see the section Store Console History Between
Sessions on page 19. The History holds up to 150,000 lines of commands.
The drop-down control menu and the right-click context-sensitive
menu are identical in the History.
Objects
The Objects is similar to the Object Explorer in the Spotfire S+ GUI.
It displays all objects for projects associated with the workspace in
two panes: a table view and an expandable tree view (the Workbench
Object Explorer).
The two panes of the Objects are linked: when the Objects table
pane has focus, items you select in the table are highlighted in the tree
pane. When the tree pane has focus, objects you select in the tree are
also highlighted in the table pane. (If you select an object member in
the tree pane, its corresponding object is highlighted in the table
pane.)
Figure 2.3: Spotfire S+ Workbench Objects.
Objects control and right-click menus
You can use the Objects control menu (click
following tasks:
) to perform the
•
Select another database.
•
Refresh the view on the currently-active database.
71
Chapter 2 The TIBCO Spotfire S+ Perspective
•
Remove the selected object from the currently-active
database.
•
Show or hide Spotfire S+ system objects, such as
.Last.value, .Data, and .Random.seed. (These objects are
hidden by default.)
•
Change the number of items displayed in the tree view
members.
The drop-down control menu and the right-click context-sensitive
menu are identical in the Objects.
Note
When you run code that creates objects in a Spotfire S+ script, the Objects is not automatically
refreshed to display the new objects. To refresh Objects and display newly-created objects, rightclick the Objects (or click the control menu button
), and then from the menu, click Refresh.
Warning
If you select a large database, such as splus, in the Objects, it can take a long time to display the
contents in the table and tree view panes.
Objects table
pane
The Objects includes a table pane displaying a list of the names and
types of objects in Spotfire S+ databases. The Objects table includes
the following information about each object:
•
name
•
data class
•
storage mode
•
extent
•
size
•
creation or change date.
By default, the Spotfire S+ system objects, such as .Random.seed and
.Last.value are hidden. You can display these objects by toggling
the option on the Objects control menu.
72
Spotfire S+ Perspective Views
Object Explorer
(tree view pane)
The Objects includes an expandable tree view, the Object
Explorer. (See Figure 2.4.) Objects listed in the Object Explorer
correspond to objects in the Objects table pane.
The Object Explorer displays icons representing the type of object
or object member, along with its name as a label. (These icons are the
same icons used in the standard Spotfire S+ GUI.)
You can expand the objects to display each objects’ members. By
default, the Object Explorer displays up to 25 object members at
each expandable level. You can change this default using the Objects
context-sensitive menu item, Set Max Children.
Figure 2.4: The Spotfire S+ Workbench Object Explorer.
•
Display the Set Max Children dialog to indicate the number
of object members to display in the Object Explorer. By
default, this option is set to 25.

73
Chapter 2 The TIBCO Spotfire S+ Perspective
Problems view
The Problems view is a standard Eclipse view that displays errors as
you edit and save code. For example, if you forget a bracket or a
quotation mark, and then save your work, the description appears as
a syntax error in the Problems view.
Note
Syntax problems appear in the Problems view only after you save the file.
If your code has a problem that is displayed in the Problems view,
and the view is not the active view, the Problems view tab title
appears as bold text.
To open the Script editor at the location of the problem, double-click
the error in the Problems view.

•
Copy the Problems view table to the clipboard.
•
Select all entries in the table.
•
View the properties of the problem.
These menu items are standard to the Eclipse GUI. For more
information, see the Eclipse Workbench User Guide.
Search Path
The Search Path displays the names and search path position of all
the attached Spotfire S+ databases.
Figure 2.7: Spotfire S+ Workbench Search Path.
The databases that are in your search path determine the objects that
are displayed in Objects. That is, if a database is in your search path,
the objects in that database appear in the Objects. See the section
Examining Objects on page 160. For more information about
working with the Search Path, see the section Changing Attached
Databases on page 153.
The first position in the Search Path shows the current working
directory, which can be either the workspace or the current path. You
can set a project to be the working project by right-clicking its name
in the Navigator, and then clicking Toggle Working Spotfire S+
Project. See the section Navigator on page 52, and the section Setting
the Working Project on page 151.

The instance of the S-PLUS engine runs the job and stores the
results, and then is released. Your code must be selfcontained, depending only on objects or functions already
available on the server (that is, in a loaded Spotfire S+ library)
or part of your submitted job.
•
The S-PLUS engine returns only one result (the last
requested). If your job requires more than one result, store the
results in a list object, and then retrieve the returned object
containing the results.

Default Folders
If your server request produces a large data set, we
recommend that you save it in the Results directory of the
job. (This is the default location, unless you specify an
absolute path.) You can download the file from this location,
and then view the results.
The Statistics Services view shows the folder structure for the
selected TIBCO Spotfire Statistics Services.

Chapter 3 TIBCO Spotfire S+ Workbench Debug Perspective
INTRODUCTION
The TIBCO Spotfire S+ Workbench includes the Debug perspective,
which is based on the Eclipse standard debugging perspective.
From the Debug perspective, you can observe the run-time behavior
of your program and determine the location of semantic errors. The
Spotfire S+ debugger understands features that are built into the
Spotfire S+ programming language and its associated libraries. With
the Spotfire S+ debugger, you can break (suspend) execution of your
program to examine your code and evaluate variables.
After you have written your code and resolved any syntax errors, you
can use the Spotfire S+ debugger to correct any logic errors that keep
your code from running correctly. Using the Spotfire S+ debugger,
you can:
•
Control your code testing by setting break points, stepping
into, though, and out of code, and pausing or terminating the
process at any point using the Spotfire S+ debugger features.
•
Set, disable, enable, or remove breakpoints while you are
debugging.
•
View variable and expression values at breakpoints while
stepping through your code.
•
Track resource allocation and function use.
Note
Because a significant amount of computation is required when you run a debugger, you should
expect to see Spotfire S+ running at a slower speed than usual when you toggle the Workbench
to Debug mode. Try this simple test for a demonstration:
1.
With Debug mode off, examine the results of running:
sys.time(lm(fuel.frame))
sys.time(validate()).
90
2.
Toggle on Debug mode and rerun the commands.
3.
Examine the difference.
Introduction
Figure 3.1 shows the Debug perspective’s views. This chapter
describes the options, features, and views included in the Debug
perspective.
Figure 3.1: The Debug perspective.
The Debug perspective also includes a profiler, which you can use to
inspect allocated memory and functions called, including call count
and duration. For more information about the Spotfire S+ Profiler,
see the section Profiler on page 120.
•
For tasks that walk you through using the Spotfire S+
debugger and profiler, see the section Chapter 4, TIBCO
Spotfire S+ Workbench Tasks.
•
For information about the Spotfire S+ perspective, see
Chapter 2, The TIBCO Spotfire S+ Perspective.
Note
You can create your own perspective that displays a combination of views from the perspectives,
or you can change the Debug perspective to suit your development style by adding, moving,
hiding, or closing views. For more information about customizing the views within the
perspective, see the section Changing the Spotfire S+ Workbench Perspective on page 42, or see
the section Customized Perspective Views on page 148.
91
Chapter 3 TIBCO Spotfire S+ Workbench Debug Perspective
DEBUG PERSPECTIVE OPTIONS AND PREFERENCES
When you examine the Debug perspective, examine the Spotfire S+
Workbench toolbars, menus, default options, and preferences in the
IDE.
Note that the Spotfire S+ Workbench toolbar includes the Spotfire S+
debugger buttons (as well as the Profiler button). These buttons are
described in greater detail in Table 1.5.
Figure 3.2: The Spotfire S+ Workbench toolbar.
Note
When you are in the Debug perspective, notice that the Eclipse environment displays a generic
toolbar that includes a Run button, a Debug button, and an External Tools button. These
buttons might work with other Eclipse plug-ins, but they are not intended to be used with
Spotfire S+. You can set breakpoints from the Debug view toolbar, or from several menus, and
you can run code using the Run Spotfire S+ Code button on the Spotfire S+ toolbar or from
the console.
92
Debug Perspective Options and Preferences
Setting
Preferences
From the menu, click Window Preferences to open the
Preferences dialog and examine the options. (For more information
about setting preferences, see the section Examining Spotfire S+
Preferences on page 14. For more information about Eclipse
preferences, see the Eclipse Workbench User’s Guide, available from the
Help Help Contents menu in the IDE.)
Most options in the Spotfire S+ pages of the Preferences dialog
apply to global settings in the Spotfire S+ Workbench. For example,
options controlling editor or Console text colors apply to both
perspectives. Only the Profiler page under Spotfire S+ controls
Spotfire S+ debugger behavior, and that controls only the refresh rate
for system allocations and function calls. See section Examining
Spotfire S+ Preferences on page 14 for more information.
Debug Mode
To start debugging, first activate the debugger using one of the
following methods:
•
On the toolbar, click Toggle Spotfire S+ Debugger
.
•
On the menu, click the Run Toggle Spotfire S+
Debugger.
•
On the keyboard, press CTRL+ALT+D.
After you activate the Spotfire S+ debugger, any expression you type
in the Console, or that you run by clicking Run Spotfire S+ Code
( ) on the toolbar, invokes the Spotfire S+ debugger.
Note
You can set Eclipse an option to be notified that a debug session is about to begin (that is, if you
click Debug ( ) and try to run a function in the Console that encounters any breakpoints).
1. From the main menu, click Windows Preferences.
2. Expand Run/Debug and select Perspectives.
3. In the Perspectives dialog, in the Open the associated perspective when
launching group, select Prompt. Click OK.
Using this Eclipse option, you are prompted to change to the Debug perspective with the
message box shown in Figure 3.3. Clicking Yes displays the Debug perspective with the Debug
view open and the debugging started.

Management page of the Eclipse Preferences dialog, in which you
can set options to open and close views automatically. This dialog is
also available from the Windows Preferences menu. For more
information about using this menu item, see the Eclipse Workbench
User’s Guide.
You can use the Debug view right-click menu (Figure 3.5) to perform
the following tasks:
102
•
Copy the contents of the stack.
•
Step into the code.
•
Step over the code.
•
Step one level out of the current function.
•
Resume debugging.
•
Suspend debugging.

Editor
The Debugger perspective uses the existing Spotfire S+ Workbench
editor. You can set and remove breakpoints in the Script Editor by:
•
Double-clicking the margin on the left side of the screen (to
the left of the line numbers).
103
Chapter 3 TIBCO Spotfire S+ Workbench Debug Perspective
•
By right clicking the margin, and from the menu, select
Toggle Breakpoint.
•
By using the Run Toggle Line Breakpoint menu option.
•
By pressing CTRL+SHIFT+B.
When you are debugging, if your functions call any functions in files
other than those in your workspace (including functions in a library),
you can double-click the expression in the Debug view and open a
temporary file that contains the called function. You can set
breakpoints in these functions, too.
Figure 1: A temporary file in the debugger.
You can view functions that are not defined in your workspace in one
of the following ways:
104
•
Double-click the Debug view.
•
Press CTRL+click in the Spotfire S+ Script Editor.
•
On the menu, click Spotfire S+ Find
Debug Perspective Views
•
Press CTRL+SHIFT+F
Note
•
Breakpoints that you set in functions in your workspace are associated with function and
with the file. These breakpoints persist until you remove them.
•
Breakpoints that you set in functions outside of your workspace are associated with the
functions, and not with the temporary files. They persist until you remove them.
•
Setting breakpoints in code files in the Spotfire S+ Workbench does not affect the file if
you open it in the Spotfire S+ GUI in Windows. Breakpoints are evaluated only in the
Spotfire S+ Workbench, and only when the debugger is engaged.
•
Breakpoints can be set only on a line contained within a function definition. Lines not
contained within a function cannot have a breakpoint set.
If you close a temporary file containing a breakpoint, and then rerun your function, the functions
called by your code reopen in another temporary file, and any breakpoints you set persist.
Examining
Using the Hover feature, you can position the mouse over an
Expression Values expression in the Script Editor, and then examine the expression’s
value, which appears in a tooltip. This feature is available for all
in Tooltips
expressions in the Script Editor, not just those where a breakpoint
appears; however, examining the value of an expression at a
breakpoint can be very useful.
You can limit the size of the expression that the Hover feature
evaluates by using the following Spotfire S+ command:
options(workbenchMaxDims=c(rows, columns))
See the section Hover on page 21 for more information.
You can enable or disable the hover tooltip feature in the Editor
options dialog from the Windows Preferences menu. This feature
is enabled by default.

Variables view
Displays all variables in the current frame. As you debug, at each
breakpoint or step, the debugger re-evaluates the variables. At any
breakpoint or stopping point, you can review, but not edit or alter, the
variables at the current frame.
Figure 3.8 shows the Variables view with the current variable
selected. The Details pane of this view contains variable information
that would result from calling print() on the selected variable or

Wraps the text that appears in the
Details pane.
Figure 3.10: Configure Details Area dialog.
Note
Figure 3.10 shows the Configure Details Area dialog, with which you can set the number of
characters to display. This option just controls the number displayed; it does not limit the number
of characters returned. To limit the number of text variables and expressions to return, use the
Spotfire S+ command options(workbenchMaxDims=c(rows, columns)). This option is useful if
you are working with a large number of text variables or expressions.
Setting this option also limits the size of the expression that the hover feature evaluates. For
example, if you are evaluating a large data object, and you hover the mouse over the expression,
if you do not set this option, Spotfire S+ tries to evaluate the expression on the spot.
The Variables view contains two right-click context-sensitive menus:
•
The Variables view (Figure 3.9).
109
Chapter 3 TIBCO Spotfire S+ Workbench Debug Perspective
•
The Details pane (Figure 3.12).
You can use the Variables view right-click context-sensitive menu to
perform the following tasks:
•
Select all variables in the pane.
•
Copy the selected variable.
•
Find a specified variable.
•
Set an expression watch for the selected variable. (When you
select this option, the selected variable is added to the
Expressions view.)
Figure 3.11: Variables view showing the right-click menu.
You can use the right-click context-sensitive menu in the Variables
view Details pane to perform the following tasks:

•
Find a specified string in the pane. (The Spotfire S+
Workbench does not support replacing strings in the Details
pane using the Find/Replace dialog.)
Figure 3.12: Variables view showing the right-click menu in the Details pane.
Expressions view The Expressions view displays the values of any Spotfire S+
expression. Like the Variables view, it is re-evaluated at each
evaluation pause (breakpoint or step).
Note on Expressions
An expression is any syntactical interaction that Spotfire S+ can
evaluate. Expressions persist from session to session. Spotfire S+
recognizes a wide variety of expressions, but in interactive use, the
most common are names, which return the current definition of the
named data object, and function calls, which carry out a specified
computation. Any of the following are Spotfire S+ expressions:
1:10
rnorm(5)
mean(1:10)
traceback()
If you were debugging a function, for example:
incrementByTwo <- function(x) {
* x + 2
}
you could have an expression that evaluated:
x + 2
111
Chapter 3 TIBCO Spotfire S+ Workbench Debug Perspective
at the breakpoint (denoted with the * in the above function
definition).
Note
If you leave in the Expressions view expressions that are no longer in scope for your current
debugging session, you might notice that the debugger slows significantly to evaluate the
expression that is no longer in scope. To keep the debugger from slowing down, remove
expressions that are no longer in scope for your current debugging session.
For more information about expressions, see the Programmer’s Guide,
or see the Spotfire S+ Help topic ExpressionLanguage.
The Expressions view toolbar buttons are the same as those of the
Variables view, with the addition of the Remove and Remove All
buttons. See Table 3.4 for more information.
The Expressions view contains two right-click context-sensitive
menus:
•
The Expressions view (Figure 3.13)
•
The Details pane (Figure 3.12).
You can use the Expressions view right-click context-sensitive menu
to perform the following tasks:
112
•
Select all expressions in the pane.
•
Copy the selected expression.
•
Remove the selected expression.
•
Remove all expressions in the view.
•
Add an expression to watch (opens the Add Watch
Expression dialog, in which you can provide an expression
and indicate whether to enable or disable it).
•
Re-evaluate the expressions.
•
Disable the currently-selected expression.
•
Enable the currently-selected expression (if it was previously
disabled).

not support replacing strings in the Details pane using the Find/
Replace dialog.)
Figure 3.14: Variables view showing the right-click menu in the Details pane.
Breakpoints view The Breakpoints view displays the currently set breakpoints, which
you can organize by resources, files, working sets, or just a simple list
or type. Each breakpoint displayed in the Breakpoints view shows
113
Chapter 3 TIBCO Spotfire S+ Workbench Debug Perspective
the function name (e.g., kahanAddNext), the file name (e.g.,
kahanAddNext_func.q), and the line number (e.g., [line 7]) where
the breakpoint occurs.
In addition to setting general user interface options, you can use the
Breakpoints view to manage breakpoint working sets and group
breakpoints. See the Eclipse Workbench User’s Guide for more
information.
Selecting a breakpoint displays in the Editor the associated file,
highlighting the breakpoint line. You can activate, disable, or delete
breakpoints from this view.

Chapter 4 TIBCO Spotfire S+ Workbench Tasks
SPOTFIRE S+ WORKBENCH PROJECTS
Before you begin working with files in the Spotfire S+ Workbench,
you must set your workspace and then create a project.
Setting the
Workspace
When you first launch the Spotfire S+ Workbench, you are prompted
to supply the path to your Spotfire S+ workspace.
To set the workspace
1. In the Workspace Launcher dialog (Figure 4.1), specify the
directory location where the workspace .Data and .metadata
databases will be stored.
2. Indicate whether you want to be prompted in future sessions
to identify a workspace using this dialog.
Figure 4.1: The Workspace Launcher dialog.
Changing the
Workspace
You can switch to another workspace from within the Spotfire S+
Workbench user interface.
To open a different workspace in Spotfire S+ Workbench
1. Save your work, and then click File Switch Workspace.
2. In the Workspace Launcher dialog, provide the new
workspace location.
Note
When you switch workspaces during a Spotfire S+ Workbench session, the current session
closes, and a new session of Spotfire S+ Workbench starts, using the new workspace location.
126
Spotfire S+ Workbench Projects
3. After you set the workspace, open the workbench.
Note
®
®
On Microsoft Vista and Microsoft Windows 7 , you must be elevated to the role of
administrator to specify the default directory as C:\Program
Files\tibco\splus82\users\yourname; however, it is not recommended that you use this
directory. By default, the workspace directory is C:\Users\yourname\workspace.
Workbench
First View
When you launch the workbench the first time, notice the user
interface. If you haven’t familiarized yourself with the workbench
GUI or its customization, see the section Examining the Spotfire S+
Workbench GUI on page 31.
Figure 4.2: The blank workbench.
Quick Start
Notice that the Console view, in the lower part of the screen by
default, looks like the standard Spotfire S+ GUI console. You can
type and run commands in the Console view. See the section Spotfire
S+ Workbench Console on page 49 for more information.
An easy way to display the Script Editor is to type an Edit
command in the Console view. For example:
127
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
Edit(myfunc)
opens the Script Editor with the beginnings of that function
definition. Alternatively, you can create a project or a new script file.
See the section Creating a Script on page 156 for more information.
Figure 4.3: Using Edit to open the Script Editor and create a function.
Creating a
Project
The Spotfire S+ Workbench project is a resource containing scripts
and associated files. You can use the project to control build, version,
sharing, and resource management. This section contains guidance
for creating a project in the workspace, adding a second project to a
workspace, adding a package project, and importing files into an
existing project.
Understanding
Project Options
Before you create a new project, consider the following scenarios, and
then review the Spotfire S+ Workbench options.
128
Spotfire S+ Workbench Projects
Table 4.1: Spotfire S+ Workbench project scenarios.
Scenario
Spotfire S+ Workbench Option
You are starting an empty
project with no existing files.
In the New Project wizard, specify a
project name and accept the default
project directory location.
(Note: This is the only way
to create a project that is
stored in your workspace.)
If your project is a package, navigate
through the wizard using the Next button.
In the Spotfire S+ Package tab, select
Create Spotfire S+ Package structure.
Click Finish.
Your project is created as a subdirectory
in the workspace directory. (The
Navigator view displays the .Data
directory and the .project resource but
no existing project files. Do not edit these
items.)
If your project is a package, the project is
created as a subdirectory in the
workspace directory, and the package
structure and required directories are
created, as follows:
•
.Data (Contains required
subfolders and files; do not edit
this directory.)
•
data
•
man
•
R
•
src
In addition, a stub DESCRIPTION file
is placed in the project directory and
informational README files are created
in each directory. For more information
on package directories, see the Guide to
Packages. For more information about
creating a package project, see the section
To create a package project on page 168.
129
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
Table 4.1: Spotfire S+ Workbench project scenarios. (Continued)
Scenario
Spotfire S+ Workbench Option
You have one or more
project(s), and you want to
work with the files at their
existing location.
In the New Project wizard, specify a
project name, clear the Use default
check box, and then browse to the
location of the project files. Spotfire S+
Workbench works with the files at the
specified location. (The Navigator view
displays the .project resource and all files
in the project directory.)
If you are importing the source files for a
package, all of the required directories
and are included in the project.
Note that the project cannot overlap other
projects and cannot be located under
your workspace.
You have an existing
project, and you want to
copy selected files to a
workspace directory (for
example, in the cases where
the files are kept at a remote
location, are read-only, or
where you do not want to
work with the original files).
In the New Project wizard, specify a
project name and accept the default
project directory location. An empty
project subdirectory is created in the
workspace directory. You can then import
your project files. See the section
Importing Files on page 131 for more
information.
Based on the scenario that applies to your project needs, In the
following sections, create an empty project, and then import the
Census project files (the third scenario described above).
To create the example census project
1. Click File New Project.
2. In the New Project dialog, select Spotfire S+ Project. Click
Next.
3. Provide the friendly project name, “Census.”
4. Accept the option Use default. This option creates the
project directory in the default workspace location.
130
Spotfire S+ Workbench Projects
5. Leave Create Spotfire S+ Package Structure clear (the
default).
6. Click Finish to create the project.
Figure 4.4: New Project dialog.
Note
When you create a project, you see in the Navigator view the .project resource. This resource is
created by Eclipse and contains information that Eclipse uses to manage your project. You
should not edit this file.
Importing Files
In this exercise, import the Census example, one of the examples
provided with Spotfire S+.
To import files
1. With the Census project selected in the Navigator view, click
File Import.
2. In the Import Select dialog, expand the General folder, and
then select File system. Click Next.
131
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
3. In the Import File system dialog, browse to the location of
the census project (by default, in your installation directory at
SHOME/samples/bigdata/census.)
4. Select the directory, and then click OK. The directory name
appears in the left pane, and all of the project’s files appear in
the right pane.
5. Select the folder name in the left pane to select all files, and
then click Finish to add the files to your project.
f
Figure 4.5: Import File System dialog for Census project.
Hint
You can select just the .ssc file to import if you prefer, because the script itself references the data
in these files. For the purposes of this part of the exercise, we import all files.
132
Spotfire S+ Workbench Projects
Figure 4.6 shows the Navigator with the Census project and
all its files.
Figure 4.6: Navigator showing Census project.
Note
Alternatively, you can copy files from a different location to your project directory in your
workspace. If you simply copy files, you must refresh the Navigator view to include the files in
your project and display them in the project file list. To refresh the view, right-click the project
name, and from the menu, click Refresh.
Loading a Library You work with Spotfire S+ code in the Workbench the same way you
work with it in other environments, such as the Java GUI, the
command line, or the Windows GUI. To load a library, in the
Console, simply call:
library(libraryname)
Where libraryname is the library to load.
For example, if you are working with Spotfire S+ packages, before
you get started, load the pkgutils library:
library(pkgutils)
Adding a Second
Project
In this exercise, create a project with the files for the Boston Housing
example at their existing location (the second scenario described
above), rather than importing the files into a workspace directory.
Boston Housing is an example provided in the Spotfire S+ sample
files, by default, in your installation directory at SHOME/samples/
bigdata/boston.
To add a project
1. Click File New Project.
133
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
2. In the New Project wizard, select Spotfire S+ Project, and
then click Next.
3. In the Project name text box, type “Boston Housing,” and
then clear the Use default check box.
4. Browse to the location of the Boston Housing sample
directory, by default in the SHOME/samples/bigdata
directory of your Spotfire S+ installation. Select the boston
directory, and then click OK. Click Finish to add the project.
Figure 4.7: New Project dialog, using boston files at their installed location.
134
Spotfire S+ Workbench Projects
5. In the Navigator view, the Boston Housing project appears.
This directory contains all of the files in that sample directory
location.

Copying Files
You can copy files from an existing project to a working project by
Between Projects copying their .ssc files from the original project to the working
project’s directory. Note that to see these files in your project, you
must refresh the view. To refresh the Navigator view, right-click the
project, and from the menu, click Refresh. (Restarting the Spotfire S+
Workbench does not automatically refresh the view.) Alternatively,
you can use the File Import menu command: Specify a file
system, browse to the original location of the desired file, and then
select only that file to import. (Importing a file into a project from
another location copies that file to the project folder in your
workspace.)

Adding the
Sample
Debugging
Project
In this exercise, add another project, importing the sample files, as
you did in the section To create the example census project on page
130. This second project is the project you will use later in this chapter
to practice debugging tasks.
Follow the directions for creating a project on pages 130 to page 133,
but instead of importing the Census project, import the kahanSum
project, located in your installation directory at SHOME/samples/
kahanSum.
To add the kahanSum project
1. Click File New Project.
2. In the New Project dialog, select Spotfire S+ Project. Click
Next.
3. Provide the friendly project name, “kahanSum.”
4. Accept the option Use default. This option creates the
project directory in the default workspace location.
5. Click Finish to create the project.
6. With the kahanSum project selected in the Navigator view,
click File Import.
7.
In the Import Select dialog, select File system, and then
click Next.
8. In the Import File system dialog, browse to the location of
the census project (by default, in your installation directory at
/samples/kahanSum.)
9. Select the directory, and then click OK. The directory name
appears in the left pane, and all of the project’s files appear in
the right pane.
10. Click Select All, and then click Finish to add the files to your
project.

Working Projects and Databases
WORKING PROJECTS AND DATABASES
This section describes setting working projects and changing
databases.
The Spotfire S+ Workbench provides the following ways you can
store your data objects:
•
In the working project .Data, where the objects are available
only to the project.
•
In the workspace .Data, where the objects are available to all
projects in the workspace.
You can change the .Data storage option at any time by setting any
project in the workspace as the working project, or toggling off the
working project option and writing data objects to the workspace
.Data database.
Setting the
Working
Project
When you create a workspace, a .Data database is created in the
workspace, and (after you refresh the view) the workspace path
appears in the first position in the Search Path, as shown in Figure
4.24. If you specify no working project, the Spotfire S+ Workbench
writes data objects to the workspace .Data database, and the objects
in that .Data database are available to all projects in the workspace.
Figure 4.24: Search Path with first position set to the workspace.
When you create a project and import project files, the Spotfire S+
Workbench creates a .Data in the project, sets it as the working
project, and sets the project in the first position in the Search Path.
Any objects created are added to the working project’s .Data
database.
151
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
To set the working project
1. Select the project to set as the working project.
2. From the main menu, click File Toggle Working Spotfire
S+ Project. (Alternatively, in the Navigator, right-click the
project that you want to set as the working project, and from
the context sensitive menu, click Toggle Working Spotfire
S+ Project.) Figure 4.25 shows the context menu.
Figure 4.25: Toggle Working Spotfire S+ Project on the Navigator contextsensitive menu.
152
Working Projects and Databases
The selected project is displayed as the working project. Any
objects you create are stored in the Census .Data database
until you choose another project as the working project, or
toggle off the working project, so the workspace .Data is the
database.
Figure 4.26: Census set as the working project.
Changing
Attached
Databases
Adding a
Database
Spotfire S+ recognizes libraries, modules, lists, and directories as
legitimate object databases. You can add and detach any of these
types of databases to the Search Path.
By default, the Search Path displays the full path of the working
database and all of the attached Spotfire S+ data libraries. Objects
existing in a recognized active database appear in the Objects.
Objects in an added database appear in Objects when you refresh the
view to that database. See the section Examining Objects on page
160.
To add a library
1. Right-click the Search Path.
2. From the right-click menu, click Add Library.
3. In the Attach Library dialog, type MASS. Clear the Attach

2. In the right-click menu, select Detach.
3. Examine the Search Path. The Big Data library is no longer
attached.
154
Working Projects and Databases
Refreshing the
View
When you refresh the view, any changes to the Search Path that
have not been reflected in a recent change are displayed. For
example, if you add a library by calling the load function in a Spotfire
S+ script, the change is not immediately displayed in the Search
Path.
To refresh the view
1. Using the Console, reattach the Big Data library. In the
Console, type
library(bigdata, first = T)
2. Right-click the Search Path.

SPOTFIRE S+ PROJECT FILES AND VIEWS
The Spotfire S+ Workbench recognizes *.ssc, *.q, *.r, and *.t files, all
file extensions common in Spotfire S+ code.
Creating a
Script
You can create a new Spotfire S+ script file, or you can import an
existing script file. The following two examples demonstrate both
techniques.
To create a new script file
1. Click File New Other.
2. In the Select a wizard dialog, select Spotfire S+ Script.
Click Next.
3. In the New File dialog, select the parent directory (the
Census project directory)
4. In the File name text box, type Sample.ssc.
5. Click Finish to create the file.
We won’t work with this file for this exercise, so you can either
disregard the file, or delete it from your project. Alternatively, you
can open the file, add some Spotfire S+ code, and save it in the
project.
Viewing Project
Files
The Navigator view displays the project files. In Windows, if you
have Microsoft Excel installed, you can open a CSV file in an
external window. In this project, only the files identified in Windows
Preferences in the File Extensions page open in the Script editor.
Removing files
from a project
Because the project script imports the data in the files from their
installation directory in Spotfire S+, you don’t need to have them all
in the project. However, removing an imported file deletes it from
your project directory, so remove individual files with care.
To remove a file from the Census project
1. In the Navigator view, open the Census project and select all
files except the .project file and census.demo.ssc.
2. Right-click the selected files, and then click Delete.
156
Spotfire S+ Project Files and Views
3. In the Delete Resources dialog, click Yes to remove the files
from the project. The Navigator view should now just
display the Census Project directory, the project file, and
census.demo.ssc:
Figure 4.28: Navigator view after deleting files
Editing Code in
the Script
Editor
The Spotfire S+ script is a text file that you can edit in the Script
Editor. In this exercise, just edit census.demo.ssc using the menu
items provided specifically for Spotfire S+.
To edit script code
1. In the Navigator view, double-click the file census.demo.ssc
to open it in the Script Editor and examine the script. Note
that:

Note that as you type each character, the code completion
feature displays the function names using the character string
so far. (The code completion feature reads the Search path on
startup and displays functions from all loaded libraries. It
refreshes the list periodically.) When you see the function
name you want to use, select it from the code-completion list
and press Enter to insert it into the text editor.
Note
The code completion feature works in both the Script Editor and the Console.

Running Code
You can run your Spotfire S+ script code directly from Eclipse in two
ways, which are described in the following section.
163
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
Script Running
Options
The Spotfire S+ Workbench provides the following customized
solutions for running your scripts from either the Spotfire S+
perspective or the Debug perspective.
Table 4.2: Script Editor options for running code.
Copying Script
Code to the
Console
Option
Description
Copy to Console
Available from the right-click menu in the Script
Editor and from the Spotfire S+ menu, this
option copies the selected code and pastes it into
the Console. See the section Copying Script Code
to the Console on page 164.
Run Spotfire S+
Code
Available from the Run menu, by pressing F9, on
the toolbar, and from the right-click menu in the
Script Editor. This option runs the selected code
(or all code, if none is selected), and then displays
output in the Output. See the section Running
Code and Reviewing the Output on page 166 for
more information.
Run Current File
Available from the Spotfire S+ menu. This
option runs the file that is open.
Run Next Spotfire
S+ Command
Available from the Run menu and from the
Spotfire S+ Workbench toolbar. This option runs
the currently selected S expression or, if the cursor
is not exactly on an expression, the next
expression.
The Console is an editable view (in other words, you can type
commands and run them by pressing ENTER); therefore, when you
copy script contents to the Console using Copy and Paste actions,
you must include the line return, or the script will not run. This
behavior is consistent with the Spotfire S+ Commands window, in
the Spotfire S+ GUI, which also requires a line return to run code.
Also like the Spotfire S+ Commands window, the Console
concatenates the code that runs throughout your Spotfire S+
Workbench session, so you can review and save it.
164
Spotfire S+ Project Files and Views
To run copied script code
1. From within the Census project’s script, select lines 1 - 13 in
the script. Be sure to select the line return at the end of line 13.
2. Right-click the code and click Copy to Console. The selected
code is copied immediately to the Console and runs. You do
not need to paste it in the Console.
3. Repeat steps 1 and 2 for lines 15-18.
4. Finally, repeat steps 1 and 2 for a few more lines.
(You can select all of the code, but if you do so, it appears in

Chapter 4 TIBCO Spotfire S+ Workbench Tasks
SPOTFIRE S+ WORKBENCH DEBUGGER TASKS
This section describes basic tasks you will want to know how to
perform on a simple file set.
Note
If you open a file using the File Open File menu command, and that file is not in a Spotfire
S+ Workbench project, you cannot set a breakpoint in that file.
The following instruction works with the kahanSum example, located in your SHOME/
samples/directory. To create a kahanSum project, follow the steps to create a project (see the
section Quick Start on page 127).
Kahan
Example
In numerical analysis, the Kahan summation algorithm minimizes the
error when adding a sequence of finite precision floating point
numbers. (It is also called compensated summation. This algorithm is
attributed to William Kahan.)
The Spotfire S+ Debugger example uses a simple Kahan summation
algorithm captured in two files. If you have not already done so,
create this project and import the example files. See the section
Adding the Sample Debugging Project on page 136.
The project’s two files are as follows:
Opening the
Debug
Perspective
•
kahanSum.q contains the function kahanSum.
•
kahanAddNext_func.q contains the function, kahanAddNext,
which is called by the function kahanSum.
Before using the Workbench Debugger and Profiler, you must open
the Debug perspective. If you have closed your project in the
previous exercise and want to continue practicing using the Spotfire
S+ Debugger, first re-open your project, and open the two files in the
Script Editor. Next, change to the Debug perspective.
For a more in-depth description of the Debug perspective, see the
section Debug Perspective Options and Preferences on page 92.
To open the Debug perspective
1.
188
On the perspective toolbar, click Open Perspective.
Spotfire S+ Workbench Debugger Tasks
2.
From the menu, select Debug.
Figure 4.49: The Open Perspective menu options.
The Debug perspective button appears to the left of the
Spotfire S+ perspective button, and the perspective changes
to the Debug perspective as shown in Figure 4.50.
Figure 4.50: Selecting the Debug perspective.
Now, you can toggle between the Spotfire S+ perspective and the
Debug perspective by clicking their respective buttons. The Debug
perspective button stays visible in this and future Spotfire S+
Workbench sessions, unless you close it by right-clicking its button
and clicking Close.
Launching the
debugger
To start debugging, first activate the Spotfire S+ debugger using one
of the following methods:
•
On the toolbar, click Toggle Spotfire S+ Debugger (
).
189
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
•
On the menu, click the Run Toggle Spotfire S+
Debugger.
•
On the keyboard, press CTRL+ALT+D.
After you activate the debugger, any expression you type in the
Console, or that you run by clicking Run Spotfire S+ Code ( ) on
the toolbar, invokes the debugger.
Setting
breakpoints
One of the most basic debugging tasks is setting a breakpoint. Set
breakpoints at locations in your code where you want to evaluate
variables. In this exercise, set the breakpoints in the Script Editor. For
a more in-depth description of the Script Editor, see section Spotfire
S+ Workbench Script Editor on page 57.
To set the breakpoints
1. From the Project files, open the file kahanAddNext_func.q
in the Script Editor. (Note that to work with the debugger,
your
2. Find the line in the code that reads:
correctedX <- nextX + kahanValues[["correction"]].
3. In the left margin, right-click to display the menu, and then
select Toggle Breakpoint. (Double-clicking the left margin
next to the code line also adds the breakpoint.)
4. Open the file kahanSum.q in the Script Editor.
5. Find the line in the code that reads:
kahanValues <- kahanAddNext(x[i], kahanValues).
190
Spotfire S+ Workbench Debugger Tasks
6. Repeat step 3 to put a breakpoint at this line.
Figure 4.51: Breakpoint set in the kahanSum function.
Note
Setting breakpoints in code files the Spotfire S+ Workbench does not affect the file if you open it
in the Spotfire S+ GUI in Windows. Breakpoints are evaluated only in the Spotfire S+
Workbench, and only when the debugger is engaged.
To examine your breakpoints
1. Click the Breakpoints view tab. Both breakpoints you set
appear in this view.

context-sensitive menu, click Go to File. Note that the
kahanAddNext_func.q file opens in the Script Editor, and
the line with the breakpoint is highlighted.
3. In the Breakpoints view, clear the check box next to the
kahanAddNext breakpoint. Note that the icon changes from a
solid circle to a blank circle in both the Breakpoints view and
in the Script file margin. This action disables the breakpoint in
future sessions but does not remove it.
4. Select the check box to enable the breakpoint.
5. On the Breakpoints view toolbar, click Skip All
Breakpoints ( ). Toggling this option disregards but
maintains (that is, does not remove or disable) all breakpoints
in the Breakpoints view.
6. Take some time manipulating the breakpoints using the menu
options and buttons in the Breakpoints view. For a more indepth description of the Breakpoints view, see section
Breakpoints view on page 113.
When you have finished, re-set the breakpoints in the files as
described in the section To set the breakpoints on page 190.
Starting
execution
Before you run the debugger, first initialize the objects and set the
output display option.
To initialize the objects
1. Open the file kahanAddNext_func.q in the Script Editor.
2. On the toolbar, click Run Spotfire S+ Code (
).
3. Repeat steps 2 and 3 for the file kahanSum.q.
4. In the Console, at the prompt, type the following code:
options(digits=17)
To start the debugging session
1. Engage the debugger by clicking its toolbar button (
2. Click the Debug view tab to display its contents.
192
).
Spotfire S+ Workbench Debugger Tasks
3. In the Console, at the prompt, type the following code:
kahanSum(rep(1000000000.1, 10))
Examining the
call stack
After you have started the debugging session, examine the UI:
Figure 4.53: At the first breakpoint in kahanSum.
To examine the call stack
1. Note that the Script Editor highlights the breakpoint line.
2. Note that the Debug view shows the contents of the call stack.
Figure 4.54: The Debug view containing the call stack.
To resume debugging
1. Resume debugging by clicking the Resume button (
).
193
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
2. Re-examine the Debug view, and note that the debugger
stops at the next break point: the first breakpoint in the
kahanAddNext function.
For a more in-depth description of the Debug view, see the
section Debug view on page 100.
To remove a breakpoint mid-session and resume debugging
1. You don’t need the breakpoint in kahanAddNext, so remove it.
In the Breakpoints view, select the breakpoint for
kahanAddNext.
2. On the Breakpoints view toolbar, click Remove Selected
Breakpoints ( ).
3. Click the Resume button again to run the debugger to the
next breakpoint. The code runs the for loop and stops at the
kahanSum breakpoint again. Observe the results in the Debug
view.
4. Click Resume a few more times to continue debugging to the
first calculate correction. In the next section, examine the
results of the first calculated correction.
Examining
Variables and
Expressions
As you debug, at each breakpoint or step, the debugger re-evaluates
the variables and displays the results in the Variables view. At any
breakpoint or stopping point, you can review, but not edit or alter, the
variables at the current frame.
For a more in-depth description of the Variables view, see the section
Variables view on page 106.
To examine the variables
1. Click the Variables view to display its contents.
2. In the Debug view, highlight the last line in the call stack.
3. Note that the Variables view displays the variables resulting
from the code run so far.
194
Spotfire S+ Workbench Debugger Tasks
4. Highlight a variable in the Variables view and note that its
value is displayed in the Details pane.
Figure 4.55: Variables view during debugging session.
5. On the Variables view toolbar, click the Show Type Names
button ( ). Note that the Variables view now displays the
variable type information.
Figure 4.56: Variables view showing type names for the variables.
6. Take some time examining the variables using the menu
options and buttons in the Variables view, clicking Resume
in the Debug view and watching the variables change.
Setting a
Watch
Expression
You can track variable assignments in the Variables view, and you
can track variables and expressions in the Expressions view. This
section demonstrates how to track individual variable assignments
and interesting expressions.
Note on Expressions
An expression is any syntactical interaction that Spotfire S+ can
evaluate. Expressions persist from session to session. Spotfire S+
recognizes a wide variety of expressions, but in interactive use the
195
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
most common are names, which return the current definition of the
named data object, and function calls, which carry out a specified
computation. Any of the following are Spotfire S+ expressions:
1:10
rnorm(5)
mean(1:10)
traceback()
If you were debugging a function, for example:
incrementByTwo <- function(x) {
* x + 2
}
you could have an expression that evaluated:
x + 2
at the breakpoint (denoted with the * in the above function
definition).
For more information about expressions, see the Programmer’s Guide,
or see the Spotfire S+ Help topic ExpressionLanguage.
To watch expressions
1. Right-click the Expressions view to display the contextsensitive menu.
2. From the menu, select Add Watch Expression.
3. In the Add Watch Expression dialog, type the following:
kahanValues[["sum"]]
Figure 4.57: Add Watch Expression dialog with expression added.
196
Spotfire S+ Workbench Debugger Tasks
4. Add a second expression to watch:
kahanValues[["correction"]]
5. Click the Variables view and right-click the variable x.
6. On the context-sensitive menu, click Create
Expressions.
7.
Watch
The debugger returns to the Expressions view. Note that the
variable X is now on the list.
8. Add the following two more expressions to watch:
sum(x)
sum(x)-kahanValues[["sum"]]
The first expression provides the sum of the variable x.
The second expression provides the difference between the
sum of x and the sum of kahanValues.
Optionally, restart debugging to start evaluating the expressions from
the start, pausing to see the results between the Variables view and
the Expressions view.
Figure 4.58: Evaluating expressions.
Stepping into,
over, and out
of a function
Other common debugging tasks include stepping through, over, and
out of a routine’s functions. When you step through a routine, the
debugger pauses at every function and function body, giving you the
opportunity to examine the results.This feature is also used to enter
if/else statements, for loops, while loops, and other routines.
197
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
To step into a routine
1. Click the Step Into button (
into routines and their bodies.
). Repeat to continue to step
2. Note that as you click Step Into, the code being evaluated is
highlighted in the Script Editor and is evaluated in the call
stack.
3. Keep stepping into the code until you come to an internal
function. (See Figure 4.59).
Because this function is not in your project files, note that the
function is displayed in a temporary file. (You can set a
breakpoint in such a function, and continue to evaluate it in
future debugging sessions.)
Figure 4.59: Stepping into a function displayed in a temporary file.
198
Spotfire S+ Workbench Debugger Tasks
You can also step over a function (
function (
), or you can step out of a
), using the buttons on the Debug view toolbar.
Note
If you are debugging using the Run button, rather than running a function via the Console view,
when you reach the last expression, you can find yourself in internal Spotfire S+ code. To avoid
this situation, type the name of the function and parameters in the Console view instead. See the
section Debugging Using the Run Button on page 206 for more information.
Examining
Resource
Usage
You can track resource allocation usage by engaging the Spotfire S+
Workbench Profiler.
To track resource usage
1. On the Spotfire S+ Workbench main menu, click the Profiler
button ( ) to toggle it on.
2. Click the Allocations view tab.
3. Examine the resource usage. Note that it is sorted
alphabetically by type. Click the Type column head; note that
the view is now sorted in reverse.
4. Click the Amount column head; note that the view is now
sorted by amount, smallest to largest.
5. Click Amount again; note that it re-sorts, largest to smallest.
6. Click the drop-down menu, and then
Allocations. Note that the table is cleared.
Examining
Function Calls
click
Reset
In the next section, examine the functions used in the example. You
can examine the functions either in an expandable tree view or in a
table view. (Make sure the Profiler is engaged by toggling on the
Profiler button on the main menu.)
To track functions used
1. Click the Function Calls view tab.
199
Chapter 4 TIBCO Spotfire S+ Workbench Tasks
2. Examine the tree. Note that after each function, in
parentheses, is the amount of time the function call took to
run.
3. Scroll down to the kahanAddNext function, expand the
selection, and examine the time values.
Figure 4.60: Tree view of the Function Calls view.
4. Right-click the Function
Function Tree to clear it.
Calls view and click Show
5. Examine the resulting table.
6.
Scroll down to the kahanAddNext function and review the call
count (that is, number of times called so far) and duration.

INTRODUCTION
This section provides information about using TIBCO Spotfire S+
code in the Workbench, and presents workarounds and solutions for
special cases you might encounter.
202
“Workspace in Use” Error
“WORKSPACE IN USE” ERROR
Occasionally, when you start the Spotfire S+ Workbench, you might
see an error that the workspace is already in use when you have not
been running a Workbench session.
This problem occurs when you switch computers or versions of
UNIX, and you have changes to absolute paths to a given directory.
1. Check your computer to ensure that the path listed in the
Workspace Selection dialog exists.
2. After you set the appropriate path to an existing workspace, if
the problem persists, check for a .lock file in the
WORKSPACE/.metadata directory. Delete this file.
3. If you do not find a .lock file, check the running processes to
see if old Eclipse processes are running that point to the
workspace. End the processes and try re-starting the Spotfire
S+ Workbench.
203
Chapter 5 Troubleshooting
WORKING WITH CALLS TO SPOTFIRE S+ GUI FUNCTIONS
While you are working with Spotfire S+, you might encounter
libraries or sample code that include calls to Spotfire S+ GUI
functions. For example, the nSurvival library includes calls to
guiCreate and guiRemove functions in their .First.lib and
.Last.lib objects, respectively.
To solve this problem, in .First.lib and .Last.lib functions, wrap
the code that creates and removes Windows GUI elements in
conditional statements. For example:
if(interactive() && platform() == "WIN386" &&
getenv("S_ECLIPSE") == "") {
##...Code that creates or removes Windows GUI elements...##
}
204
View is Not Visible
VIEW IS NOT VISIBLE
If you accidentally close a view, or if the view you want to see is not
visible, on the Windows Show View menu, select the view to
display. If the view to display is not on this list, click Other to display
the Show View dialog, and then select the folder, and then the view
to display.
205
Chapter 5 Troubleshooting
DEBUGGING USING THE RUN BUTTON
When you use the Run button to invoke a debug session rather than
using the Console, and you come to the last expression and click
Step, Step In, or Step Out, you can end up in internal Spotfire S+
functions that are called by your code.
This behavior occurs because any time you click Run, the expression
that Spotfire S+ runs is wrapped in a complex S expression designed
to capture parse errors, syntax errors, and so on.
To avoid finding yourself in this internal code, run the function by
typing it in the Console.
206
Subclipse Add-in Error with Workbench
SUBCLIPSE ADD-IN ERROR WITH WORKBENCH
If you are running the Subclipse add-in while you run the Spotfire S+
®
Workbench in Microsoft Windows , you might see the following
error when you switch between projects:
"Unknown problem executing expression (interrupt?)"
It is possible to remove this problem by performing an SVN Cleanup
operation in the Workbench.
