Examples

# NOT RUN {
# Create a random graph
graph <-
  create_random_graph(
    10, 22, set_seed = 1)

# Get the closeness values for all nodes from `1`
# to `10` and store in the graph's cache
graph <-
  graph %>%
  set_cache(get_closeness(.), "closeness")

# Get the graph's cache
get_cache(graph)
#> [1] 0.07142857 0.07692308 0.06666667 0.07142857

# Get the difference of betweenness and closeness
# values for nodes in the graph and store in the
# graph's cache
graph <-
  graph %>%
  set_cache(
    get_betweenness(.)$betweenness -
    get_closeness(.)$closeness)
