R is a free programming environment for data manipulation, statistical analyses and graphics that is becoming increasingly popular among ecologists. R is extremely powerful, can be readily extended to non-standard methods through the downloading of packages, and runs on a wide variety of platforms. Participants are expected to have a basic knowledge of statistics (as R is primarily a statistical package), but this was a course on how to use the software, not a course on statistical methods. The course is suitable for individuals who have never used R before as well as R-users looking to consolidate their understanding of the basics.
Our instructor was Dr. Carl Schwarz, Department of Statistics and Actuarial Science, at Simon Fraser University (http://www.stat.sfu.ca/~cschwarz).
