remove_from_series: Remove graph object from a graph series object

Description

Remove a single graph object from an array of graph objects in a graph series object.

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

# Create three graphs (using \code{magrittr} pipes)
# and create a graph series using those graphs
library(magrittr)

graph_1 <- create_graph() %>%
  add_node("a") %>% add_node("b") %>% add_node("c") %>%
  add_edges(from = c("a", "a", "b"),
            to =   c("c", "b", "c"))

graph_2 <- graph_1 %>%
  add_node("d") %>% add_edges(from = "d", to = "c")

graph_3 <- graph_2 %>%
  add_node("e") %>% add_edges(from = "e", to = "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)

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