Advanced R programming
> Although R has its quirks, I truly believe that at its heart it is an elegant and beautiful language. While R is a fairly mature language, we are still learning how to craft elegant R code: much code seen in the wild is written in haste to solve a pressing problem, and has not been rewritten to aid understanding.First of all, what a great endeavor by Hadley...if "all" he had done was produce ggplot2 (and write a great book about it), that's enough to cement his elite status. However, what I don't get is...why R? After a few days of hacking, I was able to produce some nice graphics with ggplot2, but I have to say that it was by far the hardest high-level language I've had to learn as a programmer...I haven't used it enough to love, so I'm not at the stage that I am with JavaScript. That is, I know of JavaScript's problems but know of the strengths that sometimes derive from its weirdness...and of course, JS is too ubiquitous to just ignore. However, with R, it just seems some of its quirks are just bad.I guess my question is aimed more at the angle of: how does R do the things it does so well? ggplot2 is great enough to learn R for it alone. And some of the data munging methods, such as `melt`, don't seem to have a well-supported port in all the other popular languages. I know that Python's pandas has one...Ruby does not. Is there something about R the language that makes it especially good at its data and statistical methods (in the way Matlab is geared toward matrix manipulation)? Or is it just that R was so heavily adopted by the stats community that, if they had picked another language, that language would have just as great as functionality as R does.Note: I suffer from selection bias, though...a lot of the people I chat with are data scientists, where R is so ubiquitous. It may be that Python pandas is just as good as the R libraries, but I just know more R-users than Python-users.
