R help - Sep 2010 - Determine Bounds of Current Graph

I'm having trouble determining the bounds of my current graph.  I know how
to set the bounds up front (ylim & xlim in most cases), but I would rather
be able to dynamically see what was chosen to use in later code.

Example:

library(maps)
map('state','Indiana')
map.axes()
??Something that lets me know the y-axis is from ~38 to ~42 and store this
information into a vector

Is there some way to query what the bounds of the current graph are?

Thanks!
