[R] World plots and clipping regions

[Ray Brownrigg]

Not with the code as it is provided.  However with a reasonably easy
modification to map.grid() (to return the coordinates of the red dotted
line) and a call to polygon(), what you want can be achieved.

Let me know if you need further details.
