The "standard" R libraries cover most of the stuff. There are a couple of things that are hard to do. Hadley's libraries are very popular, but saying that R base is "deprecated" or somehow "not correct" is completely wrong. Also all these libraries are somewhat tied to R data structures and often take advantage of R's peculiar evaluation rules of function arguments, which means they're not that easy to port to other languages.
