open source and R

However code readability can not be over-emphasized.  I must admit to have
written R code in such a supposedly `clever' way that I can't figure out
what I was trying to do (or how I did it) a week later...

The solution to that is to make sure this sort of code is adequately 
commented! Be as clever as you like - make your R look like a runner-up 
in the obfuscated perl programming contest if you want - but a 
well-placed comment will hopefully prevent that stupid feeling a week later.
