I encourage you to peruse the Github page of the R celebrity Hadley Wickham. While trained as a statistician and employed as a professor of statistics at Rice, he writes quite a few R packages that deal with more traditional development roles (unit testing and debugging, not to mention Plyr and GGplot): https://github.com/hadley?tab=repositories https://github.com/hadley?tab=repositories Also, Duncan Temple Lang, another professor of statistics, has done some really amazing work with R compilers and CUDA interfaces. https://github.com/duncantl?tab=repositories https://github.com/duncantl?tab=repositories http://www.omegahat.org/ http://www.omegahat.org/
