Session 0: Basics
Understanding of this material will be assumed throughout the course. Please read these introductory materials and make sure you understand them before beginning the readings for the first session.
If there is sufficient interest, a short primer on using R will be offered during the first week of the course (somewhere between May 26 and May 30). If you're interested in this, or if you have requests on what to cover during the primer, please write to AustinFrank.
