I don't understand your question. It looks like the example in ?lattice::panel.bwplot does exactly what you want (modulo using ggplot instead of lattice). Therefore it looks like creating a single column of y from the y in each data.frame, and also a single column of x from the x in each data.frame should be enough.
Here is an even simpler example y <- rnorm(20) x <- rep(1:2, each=10) library(lattice) bwplot(x ~ y, horizontal=TRUE) > On Nov 10, 2021, at 15:16, Rich Shepard <rshep...@appl-ecosys.com> wrote: > > On Wed, 10 Nov 2021, Rich Shepard wrote: > >> I have the code to create ggplot2 boxplots using two attributes (e.g., >> chemical concentration and month) from the same tibble.
