fully_disconnect_nodes_ws: Fully disconnect all nodes in a selection of nodes

Description

With a selection of nodes in a graph, remove any edges to or from those nodes.

Usage

fully_disconnect_nodes_ws(graph)

Arguments

graph

A graph object of class dgr_graph.

Value

A graph object of class dgr_graph.

Details

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().

Examples

# NOT RUN {
# Create an empty graph and
# add a path of 6 nodes
graph <-
  create_graph() %>%
  add_path(n = 6)

# Select nodes `3` and `4`
# and fully disconnect them
# from the graph
graph <-
  graph %>%
  select_nodes_by_id(
    nodes = 3:4) %>%
  fully_disconnect_nodes_ws()

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

# }
