[R] Multiple plots with single box

[Greg Snow]

One possibility is to use the cnvrt.coords function from the
TeachingDemos package.  It shows an example of putting a rectangle
across multiple plots.  You would need to create the 1st (top) plot,
find the coordinate of the top and convert that to device coordinates,
then create the rest of your plots and after making the last (bottom)
one find the user coordinates for the left right and bottom, convert the
coordinate for the top from device to current user coordinates and then
plot the rectangle.

Hope this helps,
