In a graph object of class dgr_graph, delete all nodes present in a selection.

Selections of nodes can be performed using the following select_... functions: select_nodes(), select_last_nodes_created(), select_nodes_by_degree(), select_nodes_by_id(), or select_nodes_in_neighborhood(). Selections of nodes can also be performed using the following traversal functions: (trav_...): trav_out(), trav_in(), trav_both(), trav_in_node(), trav_out_node().

delete_nodes_ws(graph)

Arguments

graph

a graph object of class dgr_graph.

Value

a graph object of class dgr_graph.

Examples

# Create a graph with 3 nodes graph <- create_graph() %>% add_n_nodes(n = 3) %>% add_edges_w_string( edges = "1->3 1->2 2->3") # Select node with ID `1` graph <- graph %>% select_nodes_by_id(nodes = 1) # Delete node in selection (this # also deletes any attached edges) graph <- graph %>% delete_nodes_ws() # Get a count of nodes in the graph graph %>% count_nodes()
