[R] How to tell if lattice is current device?

Dear R-helpers,

I have a function that adds some segments to the current plot, but if
I the current plot is made with any of the lattice functions (in my
case, levelplot),
I should use lsegments rather than segments.

How can I tell if the current device was made with plot() or e.g.
levelplot() or another lattice function?
dev.cur() does not help me, it just tells me "windows 2".

(Windows XP).
