Hello,
I'm not sure I understand. 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,
