[R] Multiple histograms in one chart

[Werner Wernersen]

Hi!

I've searched quite a while and this is probably a
very easy question: How do I 
prevent a new hist() histogram from clearing the chart
window before drawing?

I would like to have several histograms simply drawn
on each other in one chart...

Thanks for your help!
