Setting up your computer with R

NOTE: Before getting our hands dirty working with real data in R, we need to learn the basics of the R language. Even if you’ve poked around in R and seen these concepts before, I would still recommend you follow along and complete the free online interactive learning tutorial “TryR” (http://tryr.codeschool.com). This will take you through a gentle introduction to R syntax and some of the major R data structures (called vectors, matrices data.frames and lists) that we will cover in more detail in class .
