R's library support predates your timeline.

The most impactful, important packages I use were all developed after 2005: ggplot2, plyr, glmnet, gbm, reshape, knitr. Out of curiosity, which ones are you referring to? edit: I may be using the word library imprecisely here, which may be causing miscommunication. I mean 'packages', to be clear.

  Prior to those packages, R was the language in which most new statistical methods would be published. So it has had very good library support for statistics for a long time. Only more recently has it also gained excellent data manipulation support.

    Which kinda violates the principles expressed by the writers of said open source project, but I'm all for it on the basis that if I never again have to use base reshape, stack or gsub then it would be a good thing. I believe An Introduction to R specifically notes that one should use other software to provide R with appropriate data.

  glmnet, plyr, knitr, and ggplot2 were all developed by academic statisticians (some as grad students who have subsequently moved out of academia.) They didn't choose R because of the reasons you listed, but because it was already popular among statisticians, along with S-plus. (This is a bit of an educated guess, I haven't directly asked any of these people why they chose R. Maybe one of them will chime in!) ggplot2 and knitr are extremely well-executed extensions of ideas that had existed in R before: lattice and sweave; and lattice and ggplot2 are both fairly direct implementations of ideas developed in quasi-academic statistics by Cleveland and Wilkinson. I don't think I'm selling anyone's contributions short, just pointing out the packages you're talking about came out of academia and built on ideas and implementations that existed for at least a decade before your timeline. But the bigger point I was making is that CRAN (and, as pointed out by bbgm, bioconductor) and R's package system have been around a long time before that. And, unfortunately, was built with _very_ little input from software engineers. :) edit: incidentally, this is a case where the opensource ideas really help a project. SAS and Stata don't exactly encourage any motivated grad student to rewrite their graphics interface or report generation tools.

    At the time I wrote ggplot2, R really was the only game in town. But I strongly believe that R has excellent features to support data science: non-standard evaluation, NAs at a very low level, data frames, first class functions, ...

      Thanks for sharing that. Much more informative than my speculation :)
