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 (using \code{magrittr} for piping)
# # and create a graph series using those graphs
# library(magrittr)
# 
# 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
# series <- create_series(series_type = "sequential")
# 
# # Add graphs to the graph series
# series <- graph_1 %>% add_to_series(series)
# series <- graph_2 %>% add_to_series(series)
# series <- graph_3 %>% add_to_series(series)
# 
# # Get the second graph in the series
# extracted_graph <-
#   get_graph_from_series(graph_series = series,
#                            graph_no = 2)
