get_cmty_edge_btwns: Get community membership by edge betweenness

Description

Using edge betweenness, obtain the group membership values for each of the nodes in the graph.

Usage

get_cmty_edge_btwns(graph)

Arguments

graph

a graph object of class dgr_graph.

Value

a data frame with group membership assignments for each of the nodes.

Examples

# NOT RUN {
# Create a random graph
graph <-
  create_random_graph(
    n = 10, m = 22,
    set_seed = 23)

# Get the group membership values for all nodes
# in the graph through calculation of the leading
# non-negative eigenvector of the modularity matrix
# of the graph
