Get leverage centrality
Description
Get the leverage centrality values for all nodes in the graph. Leverage centrality is a measure of the relationship between the degree of a given node and the degree of each of its neighbors, averaged over all neighbors. A node with negative leverage centrality is influenced by its neighbors, as the neighbors connect and interact with far more nodes. A node with positive leverage centrality influences its neighbors since the neighbors tend to have far fewer connections.
Usage
get_leverage_centrality(graph)
Arguments
graph |
A graph object of class |
Value
A data frame with leverage centrality values for each of the nodes.
Examples
# 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 leverage centrality values
# for all nodes in the graph
graph %>%
get_leverage_centrality()
# Add the leverage centrality
# values to the graph as a
# node attribute
graph <-
graph %>%
join_node_attrs(
df = get_leverage_centrality(.))
# Display the graph's node data frame
graph %>% get_node_df()
