I am just beginning to use R. And I am just clinical endocrinologist, not statistician.

R is definitively not for casual user. Learning curve is very steep and previous experience in programming is essential. Therefore, some kind of menu system is extremely useful. I use combination of R-Commander and SciViews which is good, but some more functionality would be nice. On the other hand, function returning an object is great, as is simultaneous presence of multiple data sets.

Introductory documentation is excellent, both in electronic and paper form (books by Verzani, Dalgaard, Venables et al, Maindonald etc - not to forget Zoonekynd and The R Graph Gallery). However, package documentation is consistently cryptic (written for experts?) - examples with explanations would be nice. I believe that database of packages and methods would help to find appropriate package.

This list is impressive. People are knowledgable, opinionated, ready to help and to flame you for asking elementary question or asking how to use type III SSQ. So, speak softly and carry a beagle. Seriously, sometimes it would be quicker just to give an answer, than to flame a poor soul.
