Source: R/copy_node_attrs.R
copy_node_attrs.Rd

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.

Usage

copy_node_attrs(graph, node_attr_from, node_attr_to)

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.

Value

A graph object of class dgr_graph.
