get_s_connected_cmpts: Get nodes within strongly connected components

Description

Determine which nodes in a graph belong to different strongly connected components.

Usage

get_s_connected_cmpts(graph)

Arguments

graph

a graph object of class dgr_graph.

Value

a data frame with nodes and their membership in different strongly connected components.

Examples

# NOT RUN {
set.seed(23)

# Create a graph with a random
# connection between 2 different
# node cycles
graph <-
  create_graph() %>%
  add_cycle(
    n = 3,
    type = "cycle_1") %>%
  add_cycle(
    n = 4,
    type = "cycle_2") %>%
  add_edge(
    from =
      get_node_ids(
        x = .,
        conditions = type == "cycle_1") %>%
        sample(size = 1),
    to =
      get_node_ids(
        x = .,
        conditions = type == "cycle_2") %>%
        sample(size = 1))
