Controlling color in ggparcoord (from GGally package)

I am trying to hard-code the desired line color for a particular ggparcoord plot. For instance, when I create my ggparcoord plot below:

library(GGally)
x = d         


        

Answer 1

You should be able to map the colour (darkgreen) to a corresponding factor level (green) by adding:

+ scale_colour_manual(values = c("green" = "darkgreen"))
