graph_neighborhood_multiple: Take the union of multiple neighborhood graphs
Description
This function takes multiple vertices, creates graphs of their neighborhoods
(of order 1), and takes the union of those graphs.
Usage
graph_neighborhood_multiple(g, vs)
Arguments
g
The igraph graph object
vs
Either a character or integer vector (vertex names or indices,
respectively) for the vertices of interest
Value
An igraph graph object containing the union of all edges and vertices
in the neighborhoods of the input vertices; only the vertex attribute
name will be present
