R help - Feb 2011 - How to calculate the perimeter and common border of polygons?

Dear R-users,

Is there any way of calculating the perimeter of a polygon in a shapefile
object? Furthermore, how to calculate the length of the common border of two
polygons?
I've searched the code of spded, but could not find a hint on how to do it.
Thank you very much,
Leo.

I would suggest asking this question on r-sig-geo.
