set_edge_attrs_ws | R Documentation |
From a graph object of class dgr_graph
or an edge data frame, set edge
attribute properties for one or more edges.
This function makes use of an active selection of edges (and the function
ending with _ws
hints at this).
Selections of edges can be performed using the following selection
(select_*()
) functions: select_edges()
, select_last_edges_created()
,
select_edges_by_edge_id()
, or select_edges_by_node_id()
.
Selections of edges can also be performed using the following traversal
(trav_*()
) functions: trav_out_edge()
, trav_in_edge()
,
trav_both_edge()
, or trav_reverse_edge()
.
set_edge_attrs_ws(graph, edge_attr, value)
