R Change ggplot scatterplot colors
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

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
