The package provides numerous formatting options that can be readily utilised for plot labels. The function scales::dollar() is useful for presenting numbers that represent currency, specifying, for example, the ggplot2::scale_continuous() function with labels=dollar. The numbers being plotted here are not currency, but are used for demonstrating the functionality. Notice that comma is also used in the displayed values.
