Hi:
When I run the following command to convert a US state polygon from the maps
package to a polyset in PBSmapping, I obtain extra lines that should not be
in there.
plotMap(SpatialLines2PolySet(map2SpatialLines(map('state','maryland',interior=FALSE),proj4string=CRS("+proj=longlat
+datum=wgs84"))))
Compare to :
map('state','maryland').
I appreciate anyone's insight as to why this conversion is not working.
Thanks very much!
