> Very nice Jim, thank you. However, the (deterministic, or near-deterministic) diagonal lines in the plot, make me question the suitability of this approach. In my plot, the contour lines could be removed, and brighter colors could be used.
But perhaps, a better approach would be to model those lines... And it's not clear from the plot, if all the observations fall on a diagonal line... P.S. I'm not sure why there's a white line on the plot. Most of my testing was with PDF output, I will need to do some more testing with PNG output. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
