Thomas Lumley has just written a couple of functions that make experimentation with scales like this a lot easier. They're currently in R-devel, and will appear in R 2.1.0 next spring. If you want to play with them before that, you can get the source and the docs from https://svn.r-project.org/R/trunk/src/library/graphics/R/colorRamp.R and https://svn.r-project.org/R/trunk/src/library/graphics/man/colorRamp.Rd Duncan Murdoch ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
