Good Evening
I have spent a good deal of time reading the list and the book "Applied Spatial Data Analysis with R" and as well as trying to figure this one out but can't quite seem to get it.
I would appreciate it greatly if someone could direct me to a site (or send me an example) describing how I could do the following:

(1) I have a SpatialPolygonDataFrame (SPDF) object.
(2) I want to convert the SPDF object's polygons into a list of gpc.poly objects.
(3) I then perform a set of operations on the list of gpc.poly objects (this one works fine with a set of artificial data) giving me a second list of gpc.poly objects.
(4) I then want to convert the second list of gpc.poly objects back into a SPDF object where I can then add information into the the new SPDF@data data frame.

Any help would be appreciated.

Joe
