[R] Controlling size of boxplot when it is added in a plot

        I am trying to add a boxplot to the bottom of a histogram, right between the histogram bars and the x axis. Here is the code I am using at the moment (the par line is probably not relevant for our discussion):

hs <- hist(x, breaks = 20, plot = F)
par(mar = c(3,3,2,1))
hist(x, breaks = 20, main = NULL, ylim = c(-2, max(hs$counts))) boxplot(x, horizontal = T, axes = T, add = T, at = -1)

The problem is the following. As it is, the boxplot restricts itself to the -1 line. I would like it to occupy both the -1 and the -2 lines ( I guess more generally I would like to control how much vertical space the "embedded boxplot" occupies). I tried to set the width parameter in the boxplot, but that seemed to have no effect at all.

On an OT note, I haven't seen this way of combining a histogram with a boxplot (perhaps I haven't looked really hard). I thought it would be useful for my students to see them next to each other, to develop a feeling for what histograms might correspond to what boxplots. Is there perhaps some reason why I should avoid showing those graphs to them like that, that I am not aware of? Or just a reason why I haven't seen them combined like this much?
