R Information:

Instructions for installing R are divided into two parts (everyone needs to do this):
- Please make sure you have both R and R-studio installed by the second recitation (in time for your class).
- READ the instructions carefully. They do work, but if you skim over them or skip a step you may get very frustrated.

Professor Kester has put together some very nice videos on how to use R for most of the things we do in this class. You can find them here.
