Re: [R] Multiple histograms in one plot

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
