# R - The open source alternative

Commercial software can be prohibitively expensive. Therefore, we strongly encourage you to try the open source statistical programming language [R](http://www.r-project.org/) which runs on both Windows and Mac. You can use R like MATLAB, or you can try a myriad of preprogrammed packages for R that perform many of the same statistical procedures that are found in commercial statistical packages. There is a learning curve for R, but once you successfully master the R language you will never have to rely on obtaining an expensive commercial software license.   
  
There are volumes of helpful R resources but here are several to get you started:

- [The R website](http://www.r-project.org/)
- [A Quick and (Very) Dirty Intro to Doing Your Statistics in R](http://homes.msi.ucsb.edu/~byrnes/rtutorial.html#1)
