[R] Groups in histograms?

[Fredrik Karlsson]

Hi Gary,

I have found this, but it is not exactly what I am looking for. 
What I need is the groups to be inside of a single panel, not in
different panels.
Kind of like an histogram version of the xyplot(Y ~ X1,
groups=X2,panel=panel.superpose) command. (I hope this is correct).
