Get the authority scores for all nodes — get_authority

Get the Kleinberg authority centrality scores for all nodes in the graph.

Usage

get_authority_centrality(graph, weights_attr = NULL)

Arguments

graph: A graph object of class dgr_graph.
weights_attr: an optional name of the edge attribute to use in the adjacency matrix. If NULL then, if it exists, the weight edge attribute of the graph will be used.

Value

a data frame with authority scores for each of the nodes.

Examples

# Create a random graph using the
# `add_gnm_graph()` function
graph <-
  create_graph() %>%
  add_gnm_graph(
    n = 10,
    m = 15,
    set_seed = 23)

# Get the authority centrality scores
# for all nodes in the graph
graph %>%
  get_authority_centrality()
