This is one of things that I think ggplot does better - it's much easier to plot multiple data sources. I don't have many examples of this yet, but the final example on http://had.co.nz/ggplot2/geom_abline.html illustrates the basic idea. For the original poster ggplot2 isn't that much more convenient, because there isn't a built in rectangle geom (although it would be trivial to add one). You could use the more general polygon geom, http://had.co.nz/ggplot2/geom_polygon.html, however it currently doesn't have a lot of documentation.
