ABSTRACT

The primary and most general function for graphing is plot and there are special functions for statistics related graphing commands such as barplot, boxplot, dotchart, hist, and pie. This chapter presents a set of examples that provide an orientation to the plot command and the graphing frame. It illustrates a multitude of options while demonstrating the structure R has in place for creating exceptional graphs. Boxplots are typically used with large continuous data sets. The chapter presents an example having two boxplots and a stripchart overlay. It also explains how to adjust some features of the boxplots by using the R code.
