I was wondering, is there a way to make facet_wraps() labels cover all of the related columns in ggplot. Here is a example to show what I mean:
library(tidyverse)
p <- ggplot(mtcars, aes(wt, mpg)) + geom_point()
p + facet_wrap(~ vs+cyl, labeller = label_value)
As you can see, in the previous plot, the labels 0 and 1 are present above all of the columns, separately. I would like to modify it in a way that there is only one 0 above the first row of columns and only one 1 over the second row of columns.
