I thought this would be something like the following--simple but meaningful even when there are outliers in both tails. Though I like the seniors Tukey's boxplot and scatter plots, I had already used them the last time … Read More...

Turn R (Shiny) Scripts Into Double-clickable OS X Applications With One Line of Code
