Dear Ben, great, works fine! I guess, the error occurs because data outside the scale limits "is thrown away" as stated in ?coord_cartesian .

I'm not sure I completely understand your last paragraph, but I think you want to substitute coord_cartesian(xlim=c(-1,3)) for your scale_x_continuous() component; as discussed in the ggplot2 book, limits set on scales act differently than limits set on coordinate systems. (I'm a little surprised you get an error, though.) There's a very active ggplot2 google group that might be best for ggplot(2)-specific questions ...
