[R] ggplot2: multiple box plots, different tibbles/dataframes

[Bert Gunter]

You can always create a graphics layout  and then plot different
ggplot objects in the separate regions of the layout. See ?grid.layout
(since ggplots are grobs)  and ?plot.ggplot  . This also **may** be
useful by showing examples using grid.arrange()

https://cran.r-project.org/web/packages/egg/vignettes/Ecosystem.html

Still, I suspect that Jeff Newmiller may be right about needing to
structure your data more appropriately for what you wish to do.
