Hi all! My question is how to colour pixels by z value in persp plot in raster package. Here is an example: x <- seq(-1.95, 1.95, length = 30) y <- seq(-1.95, 1.95, length = 35) z <- outer(x, y, function(a,b) a*b^2) r1 <- raster(nrows=35, ncols=30, xmn=0, xmx=30, ymn = 0, ymx = 35) r1[] <- c(z) persp(r1) There already exist some function to produce persp plot for anothe classes, but I have no idea how deal with RasterLayer object. Thanks all! OV
