network (version 0.5-4)

is.bipartite: Test to see is the network can be interpreted as bipartite

Description

Tests to see is the network object can be interpreted as a bipartite network.

Usage

is.bipartite(x)

Arguments

x

for network, a matrix giving the network structure in adjacency, incidence, or edgelist form; otherwise, an object of class network.

Value

• a logical FALSE if the bipartite attribute of the network object is not present. Otherwise the count of the number of actors in the bipartite network. In this case, the number of nodes is equal to the number of actors plus the number of events (with all actors preceeding all events). The edges are then interpreted as nondirected.
