get_s_connected_cmpts: Get nodes within strongly connected components

In DiagrammeR: Graph/Network Visualization

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

suppressWarnings(RNGversion("3.5.0"))
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")

graph <-
  graph |>
  add_edge(
    from =
      get_node_ids(
        graph = graph,
        conditions =
          type == "cycle_1") |>
        sample(size = 1),
    to =
      get_node_ids(
        graph = graph,
        conditions =
          type == "cycle_2") |>
        sample(size = 1))

# components as a data frame of
