Is the edge a multiple edge?

Description

Determines whether an edge definition has multiple edge IDs associated with the same node pair.

Usage

is_edge_multiple(graph, edge)

Arguments

graph

A graph object of class dgr_graph.

edge

A numeric edge ID value.

Value

A logical value.

Examples

# Create a graph that has multiple
# edges across some node pairs
graph <-
  create_graph() %>%
  add_path(n = 4) %>%
  add_edge(
    from = 1,
    to = 2) %>%
  add_edge(
    from = 3,
    to = 4)

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

# Determine if edge `1` is
# a multiple edge
graph %>%
  is_edge_multiple(edge = 1)

# Determine if edge `2` is
# a multiple edge
graph %>%
  is_edge_multiple(edge = 2)
