Well one idea is:
ggplot(diamonds, aes(x = price)) + geom_density(aes(min =
-..density.., adjust= 0.5),fill="grey50", colour=NA) + facet_grid(. ~
cut) + coord_flip()
which looks like it would naturally fit with a boxplot overlaid on top
of it. However, it's currently not possible because the boxplot is
parameterised so that it is always horizontal, while the density is
vertical - in the above example I have flipped the coordinate system,
but that flips both density plot and boxplot.
