Multiple Boxplots

The default boxplot function in fact will plot multiple boxplots.

By comparing a number of variables we can see that some have quite a bit more spread than others, and their medians have different relative positions within the box.

We include the code here to generate a PDF version of the plot primarily to demonstrate how we can increase the width of the plot for a more pleasing presentation.

We could have presented the plot horizontally by setting the Roption[]horizontal option to TRUE.
