For those not familiar Ruby Koans is a fantastic platform for teaching many of the basics of programming in the Ruby language. It uses unit tests written for methods each of which describe a component of the Ruby programming language.
http://rubykoans.com/ The koans platform has become popular enough that it has been translated to a few other popular languages. Clojure - https://github.com/functional-koans/clojure-koans Python - https://github.com/gregmalcolm/python_koans Javascript - https://github.com/mrdavidlaing/javascript-koans I have been programming with R for around two years now, having come to R as a non-programmer, hoping to use it as a pragmatic solution to handeling and plotting lots of data. My skills have increased but are still certainly limited, and much of the advanced functionality remains a bit of a mystery to me. As I have learned more of other languages, particularly Ruby and Javascript, I am amazed with what can be done and with some concepts I so clearly have not learned while programming R. Take a look at Ruby Koans.
