[R] Multiple histograms in one plot

[Johann Hibschman]

Thanks, that works well.  Using "layout" also works.  I suppose I
should have experimented with those earlier, but I somehow got it into
my head that split.screen was the "modern" and "correct" way to handle
this.

The lattice package is nice, but it isn't useful to me, since each
histogram has a very different mean and standard deviation, so the
uniform treatment that is the lattice default does not work well.
(Presumably, there is a way around this.  Since layout/mfrow works for
me, I am not motivated to seek it.)

Cheers,

Johann
