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

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

# 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 calculation of # the leading non-negative # eigenvector of the modularity # matrix of the graph graph %>% get_cmty_edge_btwns()
#> id edge_btwns_group #> 1 1 1 #> 2 2 2 #> 3 3 2 #> 4 4 3 #> 5 5 2 #> 6 6 2 #> 7 7 1 #> 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_edge_btwns(.)) # Display the graph's # node data frame graph %>% get_node_df()
#> id type label edge_btwns_group #> 1 1 <NA> 1 1 #> 2 2 <NA> 2 2 #> 3 3 <NA> 3 2 #> 4 4 <NA> 4 3 #> 5 5 <NA> 5 2 #> 6 6 <NA> 6 2 #> 7 7 <NA> 7 1 #> 8 8 <NA> 8 3 #> 9 9 <NA> 9 3 #> 10 10 <NA> 10 4
