Sorry sending this again - is anyone familiar with multiple transparent wireframe plots?
I already checked the ?wireframe, but with no examples and as newcommer its hard to find out a correct code. If we set drape=F in the example: g <- expand.grid(x = 1:10, y = 5:15, gr = 1:2) g$z <- log((g$x^g$g + g$y^2) * g$gr) wireframe(z ~ x * y, data = g, groups = gr, scales = list(arrows = FALSE), drape = F, colorkey = TRUE, screen = list(z = 30, x = -60)) you get a two color pic of these layers - and what I'm actually looking for is making just the UPPER (toplayer) transparent.
