get_graph_from_series: Get a graph available in a series

Description

Using a graph series object of type dgr_graph_1D, get a graph object.

Usage

get_graph_from_series(graph_series, graph_no)

Arguments

graph_series

a graph series object of type dgr_graph_1D.

graph_no

the index of the graph in the graph series.

Examples

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

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

graph_3 <-
  graph_2 %>%
  add_node() %>%
  add_edge(from = 5, to = 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, .)

# Get the second graph in the series
extracted_graph <-
  get_graph_from_series(
    graph_series = series,
    graph_no = 2)
# }
