Retrieving Vertices Coordinates from SpatialPolygons
Dear List, I'm trying to use different R packages for my Teaching Assistantship classes. And I cam out to an (apparently) very simple problem. I would like to retrieve the vertices coordinate of a SpatialPolygon data. I know this is stored in the "coords" slot, but I can't get access to it! I tried to coerce the SpatialPolygon into a data.frame but it doesn't work.
