Is it only me who have the problem with extracting coordinates of a polygon from SpatialPolygonsDataFrame object? I am able to extract other slots of the object
Finally, I figured out that I didn't parse the output correctly. The correct way to do is bdryData@polygons[[2]]@Polygons[[1]]@coords. Mind the difference in command polygons(Polygons and polygons) and it took me ages to find out.
