It's definitely a bug, related to an attempt by panel.3dscatter to draw the lines in order of "depth". A temporary workaround (that will work only if a color is repeated a limited number of times) is to specify the colors in representations that are different (as strings); e.g., cloud(z~x*y,data=mydata,groups=y,type="l",col=c("#ff0000", "#FF0000")) -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.
