get_closeness: Get closeness centrality values

Description

Get the closeness centrality values for all nodes in a graph.

Usage

get_closeness(graph, direction = "all")

Arguments

graph

a graph object of class dgr_graph.

direction

using all (the default), the search will ignore edge direction while traversing through the graph. With out, measurements of paths will be from a node whereas with in, measurements of paths will be to a node.

Value

a data frame with closeness values for each of the nodes.

Examples

library(magrittr)

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

# Get closeness values for all nodes in the graph
get_closeness(graph)
#>    node  closeness
#> 1     1 0.07142857
#> 2     2 0.07692308
#> 3     3 0.06666667
#> 4     4 0.07142857
#> 5     5 0.08333333
#> 6     6 0.05882353
#> 7     7 0.08333333
#> 8     8 0.07692308
#> 9     9 0.06666667
#> 10   10 0.05882353

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