Get node attribute values from a selection of nodes
From a graph object of class dgr_graph, get node attribute values from
nodes currently active as a selection.
get_node_attrs_ws(graph, node_attr)
graph |
A graph object of class |
node_attr |
The name of the attribute for which to get values. |
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 named vector of node attribute values for the attribute given by
node_attr by node ID.
