Description

Obtain a data frame with detailed information on edges and their interrelationships within a graph.

Usage

edge_info(graph)

Arguments

Value

a data frame containing information specific to each edge within the graph.

Examples

# Create a node data frame (ndf)
nodes <-
  create_nodes(
    nodes = LETTERS,
    label = TRUE,
    type = c(rep("a_to_g", 7),
             rep("h_to_p", 9),
             rep("q_to_x", 8),
             rep("y_and_z",2)))

# Create an edge data frame (edf)
edges <-
  create_edges(
    from = sample(LETTERS, replace = TRUE),
    to = sample(LETTERS, replace = TRUE),
    rel = "letter_to_letter")

# Create a graph using the ndf and edf
graph <-
  create_graph(
    nodes_df = nodes,
    edges_df = edges)

# Get a data frame with information on the edges
# of the graph
edge_info(graph)
#>    from   to              rel
