get_degree_out: Get outdegree values for all nodes

Description

Get the outdegree values for all nodes in a graph.

Usage

get_degree_out(graph, normalized = FALSE)

Arguments

graph

a graph object of class dgr_graph.

normalized

set as FALSE (the default), the outdegree will be provided for each of the nodes (as a count of edges outgoing from each node). When set as TRUE, then the result for each node will be divided by the total number of nodes in the graph minus 1.

Value

a data frame with outdegree 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 outdegree values for all nodes
# in the graph
get_degree_out(graph)
#>    id outdegree
#> 1   1         4
#> 2   2         5
#> 3   3         3
#> 4   4         3
#> 5   5         2
#> 6   6         3
#> 7   7         1
#> 8   8         0
#> 9   9         1
#> 10 10         0

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

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