Delete all loop edges associated with a selection of nodes
With a selection of nodes in a graph, remove any associated loop edges.
delete_loop_edges_ws(graph)
graph |
A graph object of class |
This function makes use of an active selection of nodes (and the function
ending with _ws hints at this).
Selections of nodes can be performed using the following node selection
(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
(trav_*()) functions: trav_out(), trav_in(), trav_both(),
trav_out_node(), trav_in_node(), trav_out_until(), or
trav_in_until().
A graph object of class dgr_graph.
