I'm not really sure what you want. The goal of the colorkey is to associate a given z-value (or height) with a specific color. drape=TRUE does this, e.g., wireframe(volcano, drape = TRUE, colorkey = TRUE) Now, with shade=TRUE, e.g., wireframe(volcano, shade = TRUE) the SAME Z-VALUE CAN HAVE DIFFERENT COLORS depending on the orientation of the facet with respect to the viewing direction and the light source. So, a colorkey DOES NOT MAKE SENSE. -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.
