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
graph <-
  create_graph(nodes_df = nodes,
               edges_df = edges)
