Within a graph's internal node data frame (ndf), copy the contents an existing node attribute and create a distinct node attribute within the ndf with a different attribute name.
Arguments
- graph
A graph object of class
dgr_graph.- node_attr_from
The name of the node attribute column from which values will be copied.
- node_attr_to
The name of the new node attribute column to which the copied values will be placed.
