Pirateplot Example

The pirateplot function creates a pirateplot, a transparent (both literally and figuratively) plot for displaying continuous data as a function of 1, 2, or 3 discrete variables. Unlike traditional plots, like barplots and boxplots, the pirateplot shows both raw data (jittered points), descriptive statistics (line and/or bar), and inferential statistics (95% Bayesian Highest Density Intervals or Confidence Intervals), in one plot. While the default plot shows all these elements, the user can easily customize the transparency of each element using additional arguments.
