Hi Jim, i think you could not get my point. I did not want to put red-blue color there. I want to put a pallet which will describe the values of r. please have a look on following : http://bp0.blogger.com/_k3l6qPzizGs/RvDVglPknRI/AAAAAAAAAKo/itlWOvuuOtI/s1600-h/pairwise_kl_window60.png. Please see how a color pallate is added on the right side of this plot describing the value of red color, value of blue color etc.

Regards,

Try something like this:

require(grDevices) # for colours

x <- y <- seq(-4*pi, 4*pi, len=27)

r <- sqrt(outer(x^2, y^2, "+"))

image(x, y, r, col=gray((0:32)/32))

colors <- colorRampPalette(c('red', 'yellow', 'blue')) # create you
color spectrum

image(x,y,r, col=colors(100))
