get_cmty_louvain: Get community membership by Louvain optimization

Description

Through the use of multi-level optimization of a modularity score, obtain the group membership values for each of the nodes in the graph.

Usage

get_cmty_louvain(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(
    10, 22, set_seed = 23)

# Get the group membership values for all nodes
# in the graph through the multi-level optimization
# of modularity algorithm
get_cmty_louvain(graph)
#>    id louvain_group
#> 1   1             2
#> 2   2             1
#> 3   3             1
#> 4   4             2
#> 5   5             2
#> 6   6             2
#> 7   7             1
#> 8   8             2
#> 9   9             1
#> 10 10             2

# Add the group membership values to the graph
# as a node attribute
graph <-
  graph %>%
  join_node_attrs(get_cmty_louvain(.))
