Examples

# NOT RUN {
# Create a node data frame (ndf)
ndf <-
  create_node_df(
    n = 4,
    label = TRUE,
    type = c("A", "A", "B", "C"))

# Create an edge data frame (edf)
edf <-
  create_edge_df(
    from = c(1, 3, 3, 4),
    to = c(2, 2, 1, 3),
    rel = c("X", "Y", "Y", "Z"))

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

# Get a data frame with information about
# the graph's edges
edge_info(graph)
#>   id from to rel
#> 1  1    1  2   X
#> 2  2    3  2   Y
#> 3  3    3  1   Y
