rev_edge_dir {DiagrammeR} | R Documentation

## Reverse the direction of all edges in a graph

### Description

Using a directed graph as input, reverse the direction of all edges in that graph.

### Usage

    rev_edge_dir(graph)

### Arguments

`graph` | a graph object of class `dgr_graph`.

### Value

a graph object of class `dgr_graph`.

### Examples

    # 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()

    # Reverse the edge directions
    # such that edges are directed
    # toward the root of the tree
    graph <-
      graph %>%
      rev_edge_dir()

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