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

# NOT RUN {
# 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)
#>    id  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(.))
# }
