I know this is not quite a data visualization issue, but the boss asked for it, so I need to figure out if it is possible.

you can now use facet_wrap(~var, strip.position = "bottom"), though for some reason this results in the labels being located above the axis tick mark labels, rather than below (which I think would make more sense), as you can see from my screenshot of a small portion of my graph
If you want to have the label below, you have do to this
ggplot(zzz, aes(x = c1, y = c2)) +
facet_wrap(~ gp, scales = "free", nrow = 3, strip.position = "bottom") +
geom_point() +
theme(
aspect.ratio = 1,
strip.background = element_blank(),
strip.placement = "outside"
)
