Due to future needs, I started studying an interesting language for statistics, R. It looks very intriguing, and it has many ready to use functions for statistical and numerical tasks. I am writing a quick reference for myself in the wiki. The page is currently private, but if I can make it in proper shape I will publish it.
Update: After a bit of cleanup, I made the R quick reference page available. It is a work in progress. Updates to this page will be done according to my schedule in learning the language.
