get_pagerank: Get the PageRank values for nodes in the graph

Description

Get the PageRank values for all nodes in the graph.

Usage

get_pagerank(graph, directed = TRUE, damping = 0.85)

Arguments

graph

a graph object of class dgr_graph.

directed

if TRUE (the default) then directed paths will be considered for directed graphs. This is ignored for undirected graphs.

damping

the damping factor. The default value is set to 0.85.

Value

a data frame with PageRank values 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 alpha centrality scores for nodes
# in the graph
get_pagerank(graph)
