Get the graph's ndf filtered by a selection of nodes
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.
get_node_df_ws(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 node data frame.
