[R-sig-teaching] Example(s) of Biomodal distributions

[Randall Pruim]

I recently wrote a function for the mosaic package that makes it easy  
to generate various kinds of plots of distributions.  For example, to  
plot a Binom(30,.35) distribution, you just use:

distPlot("binom",params=list(size=30, prob=.35))

and get the attached plot (if it makes it through to the list).
-------------- next part --------------



Additional arguments let you choose between different kinds of plots  
(density, histogram, qq, cdf), and there is a heuristic to guess  
whether the distribution is discrete or continuous and to the right  
thing.

I didn't set these up to make it easy to add the shading, but I think  
I could modify things to make that possible too.   Stay tuned.
