[R-sig-Geo] How to get the coordinates (latitude/longitude) of a continent outline?

[Ben Tupper]

Hi,

Yes, I flubbed that.  I had it in my head that this...

... had Africa as a stand alone polygon, but that is not so.  Sorry for the noise.

What I need is the coordinates of Africa's outline (as a single entity), not the coordinates of countries' outlines within Africa.
