And using shape2poly does not work either.
>census_poly_sp <- shape2poly(census_sp, region.id = NULL)
Error in shape2poly(census_sp, region.id = NULL) :
No shp component in this list
The above file was read in (see below). Internal
measurements are in long lats. I can spplot and
make a KML file just fine for example.
census_sp <- readShapePoly("HD_102_census_blocks_sp.shp",
IDvar="BLKIDFP00", proj4string=CRS("+init=epsg:4326"))
Thanks,

How can I convert a "SpatialPolygons" object to a "polylist"
I have a file read in with "readShapePoly". This contains the polygon
long lats in a slot called "coords". I want to use the package "splancs"
"inout" function which works according to the doc with polygon data sets.
An example Map2Poly which works with "inout" lists itself as a class
"polylist".
Thanks,
Jim Burke
