get_betweenness: Get betweenness centrality scores

Description

Get the betweenness centrality scores for all nodes in a graph.

Usage

get_betweenness(graph)

Arguments

graph

a graph object of class dgr_graph.

Value

a data frame with betweenness scores 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 betweenness scores for nodes in the graph
get_betweenness(graph)
#>    id betweenness
#> 1   1         0.0
#> 2   2         0.0
#> 3   3         1.0
#> 4   4         0.0
#> 5   5         1.5
#> 6   6         7.5

#> 9   9         1.5
#> 10 10         0.0

# Add the betweenness values to the graph
# as a node attribute
graph <-
  graph %>%
  join_node_attrs(
    df = get_betweenness(.))
