Examples
# Create a graph with 5 nodes and
# edges between each in a path
graph <-
create_graph() %>%
add_path(n = 5)
# Delete node with ID `3`
graph <- delete_node(graph, node = 3)
# Verify that the node with ID `3`
# is no longer in the graph
graph %>% get_node_ids()
#> [1] 1 2 4 5
# Also note that edges are removed
# since there were edges between the
# removed node to and from other nodes
graph %>% get_edges()
#> [1] "1->2" "4->5"
