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).
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.

Dear R users:
I am currently teaching a course in Statistics. Can someone give an
R code(s) to create a biomodal curve(s) with shaded area of 90% and
with 5% in each tail
With many thanks
