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.    

  Is there any solution?    

  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))

What is the problem you are trying to solve? Tell me what you want to
do, not how you want to do it.
