SpatialPolygonsDataFrame holes problem
...plot(india[india$NAME == "Tamil Nadu",], col = 1:8)
#Extract centroid for a State (this works):
gCentroid(india[india$NAME == "Tamil Nadu",])
#Error arises for this State:
gCentroid(india[india$NAME == "Gujarat",])
#Error says:
#Error in createPolygonsComment(p) :
#rgeos_PolyCreateComment: orphaned hole, cannot find containing polygon for hole at index 2
#Code ends
I don't know my way around SpatialPolygonsDataFrame objects very well, and have no idea how to fix the errant hole.
Any help greatly appreciated.
Thanks
