R has high-quality libraries for just about everything. You're good to go if your need mostly involves stringing together calls to them. Main problem for me was expecting to find things like namespaces, utility classes, and other things you'd take for granted in more modern languages like Ruby or Java. I loved R for whipping out quick analysis utilities, but writing larger ones became insanely painful. I switched to Ruby for this kind of stuff. The library support isn't as good, but it's reached critical mass and the actual coding side is so much easier.
