You can obtain some transparency setting the alpha transparency. This is device
dependent though. Using the pdf device you can do this obtaining transparency
of both surfaces (the version must be at least 1.4 for semitransparent output
to be understood):
pdf("test.pdf",version="1.4")
wireframe(z ~ x * y, data = g, groups = gr,
scales = list(arrows = FALSE),
drape = TRUE, colorkey = TRUE,
screen = list(z = 30, x = -60),
par.settings = list(regions=list(alpha=0.75)))
dev.off()
See ?wireframe for the "at, col.regions, alpha.regions" arguments.
Does this suffice?
