[R] qplot and colors (Please Help)

[R. Michael Weylandt]

Hi David,

I believe you left out saying what color scheme you would prefer, so
it's hard to help, but you might be a start by looking at the
appropriate parts of Hadley's website here: http://had.co.nz/ggplot2/,
particularly the "scales" section.

Best,
Michael
