colors and palettes and things...

After trying to find if there was a color picker in the FAQs and the help, I thought I would send a post here. I was overwhelmed with all the wonderful color choices R has predefined (discovered after typing in colors()) but can't figure out what they all (by name) look like. Is there a color picker or some other method to display all those colors next to the name? I think I can put together palettes, but another question I have then regards the building of palettes (a list of variable length I can select or create myself other than the ones defined by Palette) so I can pass these colors into functions instead of having to predefine a bunch of colors myself or use the predefined colors like terrain.colors(n)? Are there groups of colors in the colors() that I can group together to make some nice palettes for drawing barplots, etc? Thanks, Jeff.
I'd like to point out some packages or code snippets that might be useful for you: # base package "grDevices": ?colorRamp example(colorRamp) # CRAN package "colorspace": library(help = colorspace) # CRAN package "RColorBrewer": library(RColorBrewer) ?brewer.pal example(brewer.pal) # see also the last two examples by Martin Maechler in # CRAN package scatterplot3d: library(scatterplot3d) ?scatterplot3d example(scatterplot3d) Uwe Ligges
