Set edge attribute values
From a graph object of class dgr_graph, set edge attribute values for one
or more edges.
set_edge_attrs(graph, edge_attr, values, from = NULL, to = NULL)
graph |
A graph object of class |
edge_attr |
The name of the attribute to set. |
values |
The values to be set for the chosen attribute for the chosen edges. |
from |
An optional vector of node IDs from which the edge is outgoing for filtering list of nodes with outgoing edges in the graph. |
to |
An optional vector of node IDs from which the edge is incoming for filtering list of nodes with incoming edges in the graph. |
A graph object of class dgr_graph.
