color tree about ggtree

[XinpengQi]

actually I was using group OTUs and I defined a cls (c1,c2 and c3).
I am asking how to color different c using specific color, for example, I wanna c1 red, c2 blue, and c3 gray.

thanks a lot

use scale_color_manual to specify the color.

require(ggtree)
nwk <- system.file("extdata", "sample.nwk", package="ggtree")
tree <- read.tree(nwk)
cls <- list(c1=c("A", "B", "C", "D", "E"),
            c2=c("F", "G", "H"),
            c3=c("L", "K", "I", "J"),
            c4="M")

tree <- groupOTU(tree, cls)
ggtree(tree, aes(color=group)) + scale_color_manual(values=c('black', 'red', 'blue', 'green', 'purple'))
