[R] how can I find actual axis limits for an existing plot?

I would like to query an existing plot to learn the actual x and y
limits of the plottable area. Is this possible? I can discover the
extreme tick mark locations but not the actual plot area limits.
Setting the limits with ylim will not help in this case because I am
overplotting an existing plot with a separate function, and I don't want
my end-user to have to pass parameters around.
