[R] ggplot2 - getting at the grobs

Dear All,

I continue trying to get several of my plotting functions to use ggplot, because I really do like the concept of the graphical objects, and working with them in the abstract. I am now trying to access the grobs to manipulate using grid. However, until now all I managed was to get the plot as a gTree object, and manipulate it as a gTree from there. The problem is that then it is no longer a ggplot, and thus I can no longer use the ggplot functions.
How to get at the grobs, without converting the ggplot into a gTree?
