You want to attribute a color number 1:7 to each element of your vector? Maybe the following will do. x <- scan(text = " 43 43 43 43 0 39 13 39 50 39 39 23 23 32 0 13 32 23 32 23 0 13 13 0 ") cols <- rep(1:7, rle(x[order(x)])$lengths)[order(order(x))] plot(x, col = cols) Hope this helps, Rui Barradas Em 21-06-2013 16:13, Suparna Mitra escreveu: > Hello R experts, > I want to define desired numbers to a vector based on the present > numbers.
