Hi all,

I have a few questions on color image in R (I'm using 0.90.1 on NT4).

1.  How do I get a color key on the plot?
2.  What I'd like to have is 0=white, 1=red, -1=blue (or any other color),
and numbers in between represented by different shade (e.g., 0.1 would be
light pink, -0.1 would be light blue, etc.).  Is this possible?

Thanks for any help any of you can provide.
