[R-sig-eco] Any R based GIS package to extract layer associations?

[Bruce Miller]

Hi all,

I am on the road away from my office and do not have ArcMap on my lap top.

I need to extract associations i.e. overlap of species distribution 
polygons with habitat and other polygons.

I have looked at Hawthorne's older Geospatial Modelling Environment and 
look for other spatial packages but can not find one that will extract 
the overlap.


Any ideas or suggestions?

Cheers,

Bruce Miller
