get_node_df_ws | R Documentation |
From a graph object of class dgr_graph
, get the graph's internal node data
frame that is filtered by the node ID values currently active as a selection.
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()
.
