how can I find actual axis limits for an existing plot?
Hi,
see ?par
You are probably interested in par("usr")

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. Thanks, Mark
