[R] Error "sufficient values in manual scale. 10 needed but only 7 provided"

[Jeff Newmiller]

Problem is in your data not matching your values, but you did not share your data. Try using the unique() function to see what values you have in your data.

I will say that when I want to assign discrete colors I always start by converting my character column in the data frame to a factor and specify the order I want to see the levels presented in that conversion step. Then the colors only need to be specified in that same order and I don't need to keep repeating the labels in multiple places.

library(ggplot2)

mpg$classf <- factor( mpg$class
                   , levels = c( "2seater"
                               , "subcompact"
                               , "compact"
                               , "midsize"
                               , "minivan"
                               , "suv"
                               , "pickup" 
                               ) 
                   )

class_colours <- rainbow( length( levels( mpg$classf ) ) )
ggplot( mpg, aes( x = classf, y = cty, colour=classf ) ) +
 geom_boxplot() +
 scale_colour_manual( name="Class", values = class_colours )
