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

[Richard M. Heiberger]

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)
