Usage

remove_from_series(graph_series, index = "last")

Arguments

graph_series

a graph series object from which the graph object will be removed.

index

the index of the graph object to be removed from the graph series object.

Value

a graph series object of type dgr_graph_1D.

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, .)

# Remove the second graph (with the name `remove`)
# from the graph series
series <-
  remove_from_series(
    graph_series = series,
    index = 2)

# Use `series_info()` function to ensure that
# the graph with the name `remove` was removed
series_info(series)
#>   graph name date_time   tz nodes edges directed
#> 1     1 <NA>      <NA> <NA>     3     3     TRUE
