[R] R rectangle boundary question

[ben@zoo.ufl.edu]

 You want to use "lwd=0" rather than "border=0".  "border" sets the border
_color_, not its width (and border=0, I believe, sets the border to the
current background color, white in this case).
  A more careful reading of ?rect would have detected this ...
