The resulting grapg is nice, but I cannot find how to change the colors in ggplot graph.

you need to manual designate the colors you want to use, then use scale_fill_manual.

rhg_cols1<- c("#000000","#F8766D","#7CAE00","#00BFC4","#C77CFF" )

ggplot()+geom_bar()+opts()+ scale_fill_manual(values = rhg_cols1)

Thanks. That's what I got from he duplicate question :) Also, I need to use `scale_color_manual` so the borders are colored the same way. I will accept you before this question is closed. :) – Karel Bílek May 17 '11 at 20:26
