[R-sig-Geo] intersection of two polygons

[Sebastien]

Dear helpers,

I need to find the intersection of two polygons. I have two overlapping 
polygons and I want to find the polygon corresponding to the common 
part. Is there a fonction, like unionSpatialPolygons which can do that. 
I have converted my polygons to "owin" and use the function 
'intersect.owin' in the pachage spatstat but it returns a binary matrice 
of class "owin" or I would prefer a polygon.

Thanks for your help,

Sébastien Ollier
