Description

Using a directed graph with a selection of edges as input, reverse the direction of those selected edges in input graph.

Usage

rev_edge_dir_ws(graph)

Arguments

graph

a graph object of class dgr_graph.

Value

a graph object of class dgr_graph.

Examples

# NOT RUN {
# Create a graph with a
# directed tree
graph <-
  create_graph() %>%
  add_balanced_tree(
    k = 2, h = 2)

# Inspect the graph's edges
graph %>%
  get_edges()

# Select all edges associated
# with nodes `1` and `2`
graph <-
  graph %>%
  select_edges_by_node_id(
    nodes = 1:2)

# Reverse the edge directions
# of the edges associated with
# nodes `1` and `2`
graph <-
  graph %>%
  rev_edge_dir_ws()

# Inspect the graph's edges
# after their reversal
graph %>%
  get_edges()
# }
