Subject: Creating ordered colors for ordered factors
In-Reply-To: <CAPkmt0NwwvPkxf58yE_hnv6z4SP6eT-VYDqgs7eepyigBkhGMQ@mail.gmail.com>
Hello,
Try the following.
g <- factor(c(rep("blue",10),rep("green",10),rep("red",10)),
levels = c("blue", "green", "red"))
plot(y~x, col=levels(g)[g])
plot(y~x, col=as.character(g))
Hope this helps,
Rui Barradas
