This guide is suitable for new R-users or advanced level R-users looking for information on specific topics. It was created using R version 3.2.2. You can find the most recent copy of R from the the R website: Download R. If your computer already has R, make sure that it is R3.0.2 or higher in order to run some packages, especially Swirl, which we use later in the guide.
