[R-sig-Geo] build polygons from ellipses, then sample points within the polygons

[Anthony Fischbach]

What I am looking for is a means to generate spatialPolygons from the ellipse
specifications (x,y or central coordinate, axis-a and axis-b length, along
with implied orientation of the two axes, which in my case are N-S, E-W). 
Is there a handy function enabling this?
