R

This webpage is intended to help people in my lab or classes to learn specific topics on R. Click on a link to the left to be directed to the relevant topic. Also, see the K/M section of this website for code written for internal use by our lab.

Nevertheless, in the open-source spirit of R, if you happen by this page and are interested in learning the R computer language, feel free to download the powerpoints, scripts, and other helpful files from my R class website: (http://psych.colorado.edu/wiki/doku.php?id=labs:learnr:home). The scripts are written such that you should be able to learn the basics of the program on your own. All you need to do is download R here.

Why learn R? R is an open-source software programming language for data manipulation, simulation, statistics, and graphics. It has become the lingua franca among statisticians, and is increasingly being used for data analysis among researchers.
