sgChVIDs: Change vertex IDs in a SpatialGraph

In SpatialGraph: The SpatialGraph Class and Utilities

Change vertex IDs in a SpatialGraph

Description

Change the field "ID" in the vertex slot, v, of a SpatialGraph. The fields v0 and v1 of the edge slot, e, are accordingly updated

Usage

  sgChVIDs(obj, IDa, IDp = NULL)

Arguments

obj	A SpatialGraph object
IDa	A vector indicating the updated vertex IDs
IDp	A vector indicating the prior vertex IDs

Details

If IDp is not provided, it is assumed that the vector of updated indexes is sorted equally to the order in which the vertices are stored in the slot v of the SpatialGraph. If IDp is provided, the mapping IDp -> IDa is used for reclassifying the vertices.

Value

A SpatialGraph object
