Hello Lib,

I think what you're trying to do is very easy using ggplot2 -- easy, that
is, once you got your hear around ggplot2 in the first place. The layering
you mention is the core feature of ggplot2. Fortunately it is
well-documented including a thin, overpriced book from Springer (which I
have, and like, but am not sure I should recommend).

Good luck,
robert
