Today we learned how to create visualizations in R with GGPLOT2 by adding layers.
We will continue with the GGPLOT2 crash course next week. Slides are available here, and in the archive.

We will also cover Tableau next week, so be sure to have Tableau installed if you want to follow along on your computer.

Here are links we talked about for RColorBrewer, which is a package that gives you color scale options for ordinal, categorical, and continuous data.
