I'm an R newbie and have searched for the answer to this to no avail.

I have a simple ggplot scatterplot that I set the color to "cluster" of which there are 3. The plot comes out great and is colored in 3 shades of blue. I want the colors to be dark blue, orange, and green. How do I do this? I've been toying with scale_color_manual and cannot get anything to work.

Cheers Jeff

Possibly cluster is a numeric variable, then ggplot uses scale_color_continuous. Try converting "cluster" to character or to factor and then try scale_color_manual

What does your data/code look like? You scale_color_manual should look like this:

scale_color_manual(values=c("blue", "orange", "green")
