Memberships in components

Description

These functions create a vector of nodes' memberships in components:

• node_in_component() assigns nodes' component membership using edge direction where available.

• node_in_weak() assigns nodes' component membership ignoring edge direction.

• node_in_strong() assigns nodes' component membership based on edge direction.

In graph theory, components, sometimes called connected components, are induced subgraphs from partitioning the nodes into disjoint sets. All nodes that are members of the same partition as i are reachable from i.

For directed networks, strongly connected components consist of subgraphs where there are paths in each direction between member nodes. Weakly connected components consist of subgraphs where there is a path in either direction between member nodes.

Usage

node_in_component(.data)

node_in_weak(.data)

node_in_strong(.data)

Arguments

.data

A network object of class mnet, igraph, tbl_graph, network, or similar. For more information on the standard coercion possible, see manynet::as_tidygraph().

Value

A node_member character vector the length of the nodes in the network, of group memberships "A", "B", etc for each node. If the network is labelled, then the assignments will be labelled with the nodes' names.
