Use a function that does accept the a parameter that does what you expect from log? Perhaps contourplot from the lattice package which has an extremely versatile scales parameter. Or the stat_contour() geometry in ggplot2? I did not find a scale or a log argument but there was an example at Hadley's webpage that used a scale modification to the z value. This experiment based on that that example seemed to create the expected behavior: library(ggplot2) volcano3d <- rename(melt(volcano), c(X1="x", X2="y", value="z")) v <- ggplot(volcano3d, aes(x=x,y=y,z=z)) v + stat_contour() +scale_x_log10() +scale_y_log10() -- David Winsemius ______________________________________________ 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.
