Hello! Some CS-guys (the type who knows what Church formalism is) keep asking me questions about formal definitions of R-language that I can not answer (or even understand). Is there some freely available papers which I can throw at them where it would be explained is R functional/OOP/procedural language, does it use weak/strong, dynamic/static typization, does it use lazy or ...(do not know what) evaluation, what sort of garbage collector it uses? Thanks.
R ships with a draft version of the manual "R Language Definition". Another source is Venables & Ripley (2000): S Programming, Springer.
Tell the "CS-guys" to grab the source code and chew on the LALR
context-free grammar stuff in the file "gram.y" as in:
R-1.7.1/src/main/gram.y
