[R] Lattice: finding out xlim within panel function

[Lutz Prechelt]

Dear Lattice bit-meddlers,

while within a panel function for xyplot, how can I 
find out the values of (effectively) xlim and
ylim -- no matter whether they have been set
explicitly or chosen by Lattice itself?

I have just tried for an hour to find out, 
with no success whatsoever.
I looked in Grid for something that would
return such data, but got lost.
I looked at tracebacks of panel calls, but
couldn't see the forest for the trees.

Lonely, sad, and crying...
;-)
