Copy an edge attribute column and set the name
Within a graph's internal edge data frame (edf), copy the contents an existing edge attribute and create a distinct edge attribute within the edf with a different attribute name.
copy_edge_attrs(graph, edge_attr_from, edge_attr_to)
graph |
A graph object of class |
edge_attr_from |
The name of the edge attribute column from which values will be copied. |
edge_attr_to |
The name of the new edge attribute column to which the copied values will be placed. |
