Get the closeness centrality values for all nodes in a graph.
Examples
# Create a random graph using the
# `add_gnm_graph()` function
graph <-
create_graph() %>%
add_gnm_graph(
n = 10,
m = 12,
set_seed = 23)
# Get closeness values for all nodes
# in the graph
graph %>% get_closeness()
#> id closeness
#> 1 1 0.05263158
#> 2 2 0.06250000
#> 3 3 0.05555556
#> 4 4 0.06666667
#> 5 5 0.06666667
#> 6 6 0.04166667
#> 7 7 0.04347826
#> 8 8 0.05555556
#> 9 9 0.04166667
#> 10 10 0.04545455
# Add the closeness values to
# the graph as a node attribute
graph <-
graph %>%
join_node_attrs(
df = get_closeness(.))
# Display the graph's node data frame
graph %>% get_node_df()
