[R] Formal definitions of R-language.

[M.Kondrin]

Dear Richard A. O'Keefy, Peter Dalaard BSA, Thomas Lumley, Murad Nayal, 
Douglas Trainor, Uwe Liggs!
Thanks you once more!
Your answers are very interesting and the referencies you have provided 
will keep quiet those CS-guys for a while. Your answers themselves are a 
very good informal introduction (even for non-specialist like me) to 
formal basic of R-language. Hope you would not mind if I publish this 
thread at my site (http://www.hppi.troitsk.ru/Kondrin/index.htm) with a 
title something like "What is R?"
