add: Adding and copying attributes from one graph to another

Description

These functions allow users to add attributes to a graph from another graph or from a specified vector supplied by the user.

Usage

add_node_attribute(object, attr_name, vector)
add_tie_attribute(object, attr_name, vector)
copy_node_attributes(object, object2)
join_ties(object, object2, attr_name)

Arguments

object

An object of a migraph-consistent class:

• matrix (adjacency or incidence) from {base} R

• edgelist, a data frame from {base} R or tibble from {tibble}

• igraph, from the {igraph} package

• network, from the {network} package

• tbl_graph, from the {tidygraph} package

attr_name

Name of the new attribute in the resulting object.

vector

A vector of values for the new attribute.

object2

A second object to copy nodes or edges from.

Functions

• add_node_attribute(): Insert specified values from a vector into the graph as node attributes

• add_tie_attribute(): Insert specified values from a vector into the graph as tie attributes

• copy_node_attributes(): Copies node attributes from a given graph into specified graph

• join_ties(): Copies ties from another graph to specified graph and adds a tie attribute identifying the ties that were newly added
