[R] ggplot and colors

[Adel ESSAFI]

Hello,
I have a problem with ggplot and colors

I used this function to draw somes lines and I want them to be all black
(just to test)
however, I dont get any black line in the figure.

Do you have any experience with ggplot and manual colors??



ggplot(cmax, aes(cmax[,3], cmax[,6],colour=interaction(cmax[,1],cmax[,2])))
+ geom_line() +  geom_point() +  scale_fill_manual(values=c("black",
"black" , "black", "black", "black", "black", "black", "black", "black",
"black", "black", "black" ))


best regards
