This is false of course. What you meant to say (I hope) is that you
can use the grid package to annotate any plot drawn **with grid
graphics** any way you light. This includes both the lattice and
ggplot packages. As you said, the exact details of how to do it may
not be exactly transparent (and I don't know whether they are or not
in this case).

Graphics drawn with the base graphics functionality are generally
incompatible with grid graphics.

Cheers,
