Is there a cleaner way to check all IDs of a spatialPolygons object? I know how to do it with one:
slot(spol at polygons[[2]],"ID")
[1] "g2" and for all of them I use
sapply(spol at polygons,slot,"ID")
is there something more straightforward, sort of spFIDs() (by analogy to spChFIDs() )?
row.names(spol), OK? Roger
Thanks Agus
