get_coreness: Get coreness values for graph nodes

Description

Get the coreness values for all nodes in a graph.

Usage

get_coreness(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 coreness values for each of the nodes.

Examples

# NOT RUN {
# Create a random graph using the
# `add_gnm_graph()` function
graph <-
  create_graph(
    directed = FALSE) %>%
  add_gnm_graph(
    n = 10,
    m = 15,
    set_seed = 23)

# Get coreness values for
# all nodes in the graph
graph %>%
  get_coreness()

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

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