[R-sig-Geo] shape of circles

[Agustin Lobo]

Hi!

I have to create a shp of "circular" polygons
out of a file with x,y coordinates and radii.

I've found that disc() from package GRID makes
an owin object for each circle, but then how can
I convert to sp (from there to shp using writeOGR)?

Thanks

Agus
