[R] Current R color chart

[Rich Shepard]

I have an R color chart downloaded from the Web March 4, 2015. Using it to
set ggplot2 colors R responds with 'Error: Unknown colour name: FF3030' for
a number of these colors.

There are several different color charts for R when I look for a new one but
I cannot tell which one has all colors recognized by the latest R version.
