Just a short note on what I just discovered on the Internet, looking for some R stuff. It turns out, there is something like R-Commander. In simple words- R with pull-down menus and basic features, something like R for Dummies :). And by basic features I mean data summaries and graphs, t-test, ANOVA, clusters, PCA, distributions and some more!
I am installing it on my computer right now. All you need to do is to install package Rcmdr, and load it. If you are missing any packages (quite many, in my case), you get a message and R takes care of it by itself.
R-Commander itself seems to be rather intuitive and easy to use.
