Usage

graph_count(graph_series)

Arguments

Examples

# NOT RUN {
# Create three graphs
graph_1 <-
  create_graph() %>%
  add_n_nodes(3) %>%
  add_edges_w_string(
    "1->3 1->2 2->3")

graph_2 <-
  graph_1 %>%
  add_node() %>%
  add_edge(4, 3)

graph_3 <-
  graph_2 %>%
  add_node() %>%
  add_edge(5, 2)

# Create an empty graph series and add
# the graphs
series <-
  create_series() %>%
  add_to_series(graph_1, .) %>%
  add_to_series(graph_2, .) %>%
  add_to_series(graph_3, .)

# Count the number of graphs in the graph series
graph_count(series)
#> [1] 3
# }
