[Rd] using a factor as col argument in plot:

Dear R core team

Using the following code produces an empty plot (similar to col = NA):

> plot(1:9, col = factor(rep(1:3,3), labels = c("red", "blue", "black")))

My question: Shouldn't one get at least a warning (or an error)

             if one tries to use a factor as col argument?

Thanks for an answer.
