I'll check that book out and/or get help from the authors. But i was still hoping there is some basic way to compare these 3d plots using R. By the way, I figured out i can draw these plots using command "image" and get a gradient heat map or topography map with gradients. Is there a function in R to process the colors in these images and give me the difference between two images? -- View this message in context: http://r.789695.n4.nabble.com/Compare-two-3d-plots-tp2716325p2717123.html Sent from the R help mailing list archive at Nabble.com.
