obj

an object.

value

(integer vector, NA allowed, NULL or empty integer vector allowed) mapping of old group numbers to new ones. The length must be exactly equal to the number of old groups in the object. The old numbers match the positions of the index, and the new ones are the values in the vector. For example, c(2, 1) maps 1->2 and 2->1; c(3, 2, 1) maps 1->3, 3->1 and 2 stays unchanged; '1:2' has no effect; NOTE: c(1, 1) merges groups 1 and 2 into 1! If the 'geo.group' is NA in the object, its value will be NOT changed. If the data has only NAs, the only mapping that is allowed is an empty vector, resulting in no change in the original object. The special value '0' (group of excluded geos) will also be unchanged.

An object identical to 'obj' except the 'geo.groups' column has (possibly) changed.

If all group ids in 'geo.group' are NA, nothing changes as 'NAs' cannot be mapped. Try 'SetGeoGroup<-' instead, to map specific geos first into group ids.
The group number '0' (group of excluded geos) remains unchanged. It is not possible to map this group to another. For that purpose, map geos explicitly to desired groups using the replacement method 'SetGeoGroup<-'.
It is however possible to exclude a complete group by mapping it to 0 by including 0 in the map, for example c(1, 2, 0) maps group 3 to 0, leaving group numbers 1 and 2 unchanged.
