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)
