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

library(magrittr)

# Create a random graph
graph <-
  create_random_graph(
    10, 22, set_seed = 1)

# Get the betweenness scores for nodes in the graph
get_betweenness(graph)
#>    node betweenness
#> 1     1    6.633333
#> 2     2    5.638095
#> 3     3    1.904762

#> 9     9    3.466667
#> 10   10    1.166667

# Add the betweenness values to the graph
# as a node attribute
graph <-
  graph %>%
  join_node_attrs(
    get_betweenness(.),
    by_graph = "nodes",
    by_df = "node")
