(I had been meaning to reply, but it slipped my mind.) I can't see an easy way to do this for persp, but it's technically possible (though not a one-liner) for cloud and wireframe. I can look into it if you think it will help. -Deepayan ______________________________________________ R-help@r-project.org 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.
