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

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

# Create a random graph using the # `add_gnm_graph()` function graph <- create_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 the multi-level # optimization of modularity # algorithm graph %>% get_cmty_louvain()
#> id louvain_group #> 1 1 2 #> 2 2 1 #> 3 3 1 #> 4 4 3 #> 5 5 1 #> 6 6 1 #> 7 7 2 #> 8 8 3 #> 9 9 3 #> 10 10 4
# Add the group membership # values to the graph as a # node attribute graph <- graph %>% join_node_attrs( df = get_cmty_louvain(.)) # Display the graph's # node data frame graph %>% get_node_df()
#> id type label louvain_group #> 1 1 <NA> 1 2 #> 2 2 <NA> 2 1 #> 3 3 <NA> 3 1 #> 4 4 <NA> 4 3 #> 5 5 <NA> 5 1 #> 6 6 <NA> 6 1 #> 7 7 <NA> 7 2 #> 8 8 <NA> 8 3 #> 9 9 <NA> 9 3 #> 10 10 <NA> 10 4
