UCLA Statistics has a pretty extensive list of resources on how to use R and GRASS. For those unfamiliar, R is a programming language and environment for statistical computing and graphics. GRASS is an open source geographic information system (GIS). And of course, both are completely free and completely useful.
Thanks Nathan! I appreciate the addition. There is also a section on LaTeX now and I will be adding Python over Winter Break.
Due to classes, I’ve fallen behind on making sure all of the links are still functioning, but a couple of scripts will take care of that. It is still an infant, but I am hoping to incorporate it in a potentially larger project that will have a better URL :-)
