label aesthetic for outliers #14
Description
Like boxplots, bagplots obtain outliers. As discussed in #13 , it can be useful to focus on these outliers in the plot.
This feature is not provided in {ggplot2} or in any extensions. See this SO thread for an illustration using a custom is_outlier() function, which would be too cumbersome in the bivariate setting, especially given that other methods (e.g. convex hulls) will also obtain outliers.
A solution in {gggda} would be to introduce the label aesthetic and a synchronized outlier.label parameter to geom_bagplot().
