Hi All, I am looking for references on R as a programming language (apart form the standard R-lang.pdf and the other manuals), reference that would cover _in_depth_ things like loops, code optimisation, debugging tools etc... and is as up-to-date as possible. Can anyone suggest any book or other reference apart from the "green book" and the V&R "S-programming"?
I think you've already got the best references.
There is always the source. In a sense, it IS the most in-depth and up-to-date description of the intricacies of using the language, though it isn't as easy to read as V&R's S Programming. In-depth and up-to-date are tradeoffs rather than being complementary.
I don't know what Federico Calboli has in mind, but as for myself, upon starting with R, I've been looking for an R language reference in the style of the Python reference (http://docs.python.org/ref/ref.html). The specification of the grammar and the associated semantics of a language gives me the kind of in-depth conceptual understanding that I like to have, and I find this more difficult to accrue for R than for other languages. For example, I'm still not certain whether I'm able to correctly predict how many copies of an object are created during the execution of some code, and consequently, I'm not really confident that my code is reasonably optimal. I'd appreciate pointers to any (more or less hidden) gems I may have overlooked, of course. Best regards, Jan
