get_pagerank: Get the PageRank values for all nodes

Description

Get the PageRank values for all nodes in the graph.

Usage

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

Value

A data frame with PageRank values for each of the nodes.

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.

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 PageRank scores
# for all nodes in the graph
graph %>%
  get_pagerank()

# Colorize nodes according to their
# PageRank scores
graph <-
  graph %>%
  join_node_attrs(
    df = get_pagerank(graph = .)) %>%
  colorize_node_attrs(
    node_attr_from = pagerank,
    node_attr_to = fillcolor,
    palette = "RdYlGn")
