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