What would I do if I have something like:
x <- rnorm(1:1000)
y <- rnorm(1:1000)
z <- x + y
and I want the rainbow to increase with z? (i.e., red for lowest z...all
the way up to the last color in the rainbow for the highest z)
-----------
I can't help w/ a 3-d function directly, but my cute little tool
clplot() will do exactly that for any pair of x, y vectors. It's
available in the latest plotrix package.
The code is not very complicated, so I'd imagine you could rewrite it to
handle z= f(x,y) on your own :-)
