get_cmty_l_eigenvec | R Documentation |
Through the calculation of the leading non-negative eigenvector of the modularity matrix of the graph, obtain the group membership values for each of the nodes in the graph.
get_cmty_l_eigenvec(graph)

A graph object of class |
A data frame with group membership assignments for each of the nodes.
# Create a random graph using the
# `add_gnm_graph()` function
graph <-

directed = FALSE) %>%
add_gnm_graph(
n = 10,
m = 15,
set_seed = 23)
# Get the group membership
# values for all nodes in the
# graph through calculation of

# eigenvector of the modularity
# matrix of the graph
graph %>%

# Add the group membership
# values to the graph as a node
# attribute

# Display the graph's node data frame
