R - Statistics Software
R is an open source mathematical language used in many of the places that statistical programs like SPSS or SAS
are used. Because it is a free, open source program it can be installed on any machine without needing to worry
about license agreements.
To use the full power of R, one writes a series of commands telling R what to do. These can either be one at a time
or as a set of commands in a text file.
For example, to load in a file of results, pick out the results from particular days, get a random subset of a million of
the samples, then do a scatter plot of two variables in these million observations, you might write the instructions:
> mydata <- read.csv(“results.txt”)
> mysubset <- subset(mydata, mydata$days==16 | mydata$days==18 | mydata$days==20 | mydata$days==22 |
mydata$days==24 | mydata$days==26 | mydata$days==28)
> myrandommillionsubsample <- mysubset[sample(1:dim(mysubset)[1], size=1000000, replace=FALSE),]
> qplot(myrandommillionsubsample$green, myrandommillionsubsample$red, shape = myrandommillionsubsam
ple$substance, method = ‘lm’, colour = myrandommillionsubsample$substance)
R (continued)
However, when coming to grips with R, some people prefer to use GUI with windows and menu commands. This
is similar to getting the full power of SPSS by typing your own commands, or using what is available via the menu
options.
In R, a GUI called R Commander gives easy access to most of the R commands.
Because it is open source, interested people can develop it in a number of different ways, one of which is the
version Red-R. In Red-R, you clip together the steps you want to perform on the data as a flowchart, which you can
save for future use.
