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) library(rgl) ym = xtabs(y~x1+x2) persp3d(as.numeric(rownames(ym)),as.numeric(colnames(ym)),ym, xlab="x1",ylab="x2",col="gray") 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). http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-3d:graphics-3d good luck Ben Bolker ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
