get_radiality: Get radiality centrality scores

Description

Get the radiality centrality for all nodes in a graph. These scores describe the ease to which nodes can reach other nodes.

Usage

get_radiality(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 radiality centrality 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 radiality scores for nodes in the graph
get_radiality(graph)
#>    id radiality
#> 1   1  2.888889
#> 2   2  2.888889
#> 3   3  2.888889
#> 4   4  2.666667
#> 5   5  3.000000
#> 6   6  3.222222
#> 7   7  2.777778
#> 8   8  2.555556
#> 9   9  3.000000
#> 10 10  3.000000

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

# Display the graph's node data frame
get_node_df(graph)
