Using a pre-defined color palette in ggplot

Question

Does anyone know how to use a pre-defined color palette in ggplot?

I have a vector of colors I would like to use:

rhg_cols <- c(\"#771C19\", \"#AA         


        

Answer 1

First add, the colours to your data set:

mydata$col <- rhg_cols

Then map colour to that column and use scale_colour_identity

ggplot(mydata, aes(factor(phone_partner_products, colour = col))) + 
  geom_bar() + 
  scale_colour_identity()
