Using Windows with R 2.0.1 this looks fine at first. But when I resize the graphic, copy the graphic to a metafile and paste it into Word, or go to an earlier graphic and come back using "History", the colors ae all messed up. It's as if only the last palette is being used for all four plots in the figure. Oddly, if I copy the graphic as a bitmap, the colors are preseved in the bitmap. Is this a quirk of my machine or does this happen for others? Is it possible that the Windows palette manager is being used (which is such about obsolete) and that true color graphics are not being used (which is the easist way to avoid headaches from the Windows palette manager)? efg ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
