sab-R-metrics: Intermediate Boxplots and Histograms

Last week, I began talking about using the base graphics in R. Those graphics were pretty bland, and my hope for the next two posts is to introduce some interesting additions to the basic graphics that come from R: color, legends, lines, shapes, multiple graphs side-by-side, text, point types, and custom axes. If you have missed...
