Important: The networks package has been deprecated .Use the superseding package GraphTheory instead.

Given a vertex v the degree of v in G is returned.

Undirected and directed edges may both exist, but vdegree uses only the undirected edges. Use indegree() or outdegree() to determine the other kinds of degrees.

This routine is normally loaded via the command with(networks) but may also be referenced using the full name networks[vdegree](...).
