Description

Counts the total number of graphs in a graph series object.

Usage

graph_count(graph_series)

Arguments

graph_series

Value

a numeric vector representing a count of graphs in a graph series object.

Examples

library(magrittr)

# Create three graphs
graph_1 <-
  create_graph() %>%
  add_node("a") %>%
  add_node("b") %>%
  add_node("c") %>%
  add_edge("a", "c") %>%
  add_edge("a", "b") %>%
  add_edge("b", "c")

graph_2 <-
  graph_1 %>%
  add_node("d") %>%
  add_edge("d", "c")

graph_3 <-
  graph_2 %>%
  add_node("e") %>%
  add_edge("e", "b")

# 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)
