Where is that documented?  In the help file, I see this:


width, height: the width and height of the plotting window, in inches. 
          If 'NA', taken from the resources and if not specified there
          defaults to '7' inches.  See also 'Resources'.

That's what works on my machine.  Just what happens if you specify
dimensions larger than the screen seems to be undocumented and I would
expect the unexpected and that's what you got.
