Session 0: Basics with optional R primer

11:00, May 27 2008

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.

This optional meeting of the course will be an R primer. We'll be focusing on obtaining a basic level of familiarity required to participate in the course. We won't cover everything you'll need to know for the course, but hopefully we'll cover enough that you will be able to learn new material on your own.

If there are things you would like to cover, please make note of them below. NB: as of now there are no plans to teach graphing functions during the primer.

Reading

Baa08	Chapter 1 (pp. 1-20)	Intro to R.
