# 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"
