select by histogram or boxplot

[topepo]

For showing observed outcomes vs predictions, we are going to have plots that visualize a categorical variable (true outcome or some qualitative predictor) versus a numeric column (see this code block for example).

If we use histogram or boxplots, can ggplotly() be used to select boxes or histogram bars to select data?

We can do the linking on histogram but we haven't done it yet.
