| delete_edges_ws {DiagrammeR} | R Documentation |
In a graph object of class
dgr_graph, delete all edges present in a
selection.
Selections of edges can be performed using
the following select_... functions:
select_edges(),
select_last_edge(), or
select_edges_by_node_id().
Selections of edges can also be performed using
the following traversal functions:
trav_out_edge(), trav_in_edge(),
or trav_both_edge().
