fully_connect_nodes_ws

R Documentation

Fully connect all nodes in a selection of nodes

Description

With a selection of nodes in a graph, add any remaining edges required to fully connect this group of edges to each other.

This function makes use of an active selection of nodes (and the function ending with ⁠_ws⁠ hints at this).

Selections of nodes can be performed using the following node selection (⁠select_*()⁠) functions: select_nodes(), select_last_nodes_created(), select_nodes_by_degree(), select_nodes_by_id(), or select_nodes_in_neighborhood().

Selections of nodes can also be performed using the following traversal (⁠trav_*()⁠) functions: trav_out(), trav_in(), trav_both(), trav_out_node(), trav_in_node(), trav_out_until(), or trav_in_until().

Usage

fully_connect_nodes_ws(graph)

Arguments

graph

A graph object of class dgr_graph.

Value

A graph object of class dgr_graph.

Examples

# Create an empty graph and
# then add a path of 3 nodes
# and two isolated nodes
graph <-
  create_graph() %>%
  add_path(n = 3) %>%
  add_n_nodes(n = 2)

# Select a node in the path
# of nodes (node `3`) and
# the two isolated nodes (`4`
# and `5`); then, and fully
# connect these nodes together
graph <-
  graph %>%
  select_nodes_by_id(
    nodes = 3:5) %>%
  fully_connect_nodes_ws()

# Get the graph's edge data frame
graph %>% get_edge_df()

# Create an undirected, empty
# graph; add a path of 3 nodes
# and two isolated nodes
graph <-
  create_graph(
    directed = FALSE) %>%
  add_path(n = 3) %>%
  add_n_nodes(n = 2)

# Select a node in the path
# of nodes (node `3`) and
# the two isolated nodes (`4`
# and `5`); then, and fully
# connect these nodes together
graph <-
  graph %>%
  select_nodes_by_id(
    nodes = 3:5) %>%
  fully_connect_nodes_ws()

# Get the graph's edge data
# frame; in the undirected
# case, reverse edges aren't
# added
graph %>% get_edge_df()
