Thanks for giving a reproducible example [snipped], but it's not clear
what you need to know. Are you wondering whether there are general
design standards for 3d perspective plots? (There's a little bit
in Cleveland's "Visualizing data".) I'm afraid the general answer
is "play around with the parameters until you think it looks good".
You could also try rgl:
y <- c(66,39,43,49,58,17,-5,-40,65,7,43,-22,-31,-35,-26)
x1 <- c(-1,1,-1,1,-1,1,-1,1,rep(0,7))
x2 <- c(-1,-1,1,1,0,0,0,0,-1,1,-1,1,0,0,0)
ym = xtabs(y~x1+x2)
unfortunately, there's not (yet?) any easy way to get
filled + lines on the surface; using front="line" will
get you a wireframe (see ?rgl.material).
