Hi Greg,
Probably you need to look at filled.contour(). I've managed to plot
similar graphics from netCDF files. If you need some more explanation
let me know.

Yes it looks like a really good student exercise into the sampling
properties of a distribution.
What you need to do is initialize vectors beforehand that will contain
the mean and variance values. Then simply use a for() loop that
generates 5 random numbers. Use the mean(), var() and store the va

This is not a direct answer to your question, but the book

Shapiro and Hal R. Varian (1998) describe how to wage and win a

e <- rnorm(40, 0, 1)
if(any(p==0))e[p==0] <- 3*(rchisq(sum(p==0), 1)-1)
To find out whether this is faster than what you wrote, surround it with
calls to proc.time, as follows:
