But, I saw that other mathematic frameworks (CERN ROOT for instance) can plot 3D surfaces with colors corresponding to z-value. Is there way to do this in R (with another functions/packages)? It's not necessary to use _one_ color per facet, yes?.. :) -- WBR, Timur. ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
