I’ve been meaning to post something about R for a while, but never got started, and now have a pile of things I’d like to post, so it’s time to get started.

I first started using R during my Master Dissertation where I had to do some stats.  I’ve since had several occasions needed to do some ad-hoc data analysis of one sort or another, and every time I’ve ended up using R to get it done.  I now use R regularly, and while can’t describe myself as an expert, I’d say a enthusiastic amateur.

R is an integrated suite of software facilities for data manipulation, calculation and graphical
Display.  It is a full, proper programming language, even being turing complete.  It has a suite of operators for calculations on data in many forms, in particular arrays and matrices.  It also has an enormous collection of add-on packages for pretty much any form of analysis, calculation or statistic that can be performed.

You can run R in a million different ways, the most basic is just using the basic R interpreter and the command line.  Personally I use Eclipse / StatEt / LaTex, which I’ll describe another time.

A colleague recently asked about the basics, so I’ve cribbed my email back to him here, where I suggested either Rcommander or JGR / Deducer, which both seem the ideal mid point of some extra menu/click functionality without trying to rebuild Excel in R.  Rcommander seems to be slightly better in terms of a statistics tool, and JGR/Deducer in terms of data exploration.
RCommander ( is an add-on package to R.

To Use RCommander, install R and run, then in the console, type
install.packages(“Rcmdr”, dep=TRUE)
this should install R commander.  To run it in the console type

 install.packages("Rcmdr", dep=TRUE)

this should install R commander. To run it in the console type


JGR (Java Gui for R – ) and an add-on to it, Deducer (  They’re both ‘packages’ in R, which means some extra functionality that can be easily installed from within R and then used.

To Install
Ensure you have a fairly up to date Java installed
Download and Install the latest version of R from CRAN (Comprehensive R Network – )
Download and Install the JGR client from
Start the JGR application.  It will get any extra things it needs.
The JGR console should now be open. To load Deducer, go to ‘Packages & Data’ > ‘Package Manager’ and select Deducer and DeducerExtras.
Now you’re using R !
Now you need to go find some help, I’d recommend some places to start with R;
