simplify_topology: Remove all 2-degree nodes from a graph

In dSHARP-CMU/pathfinder: Topology Navigation And Manipulation Functions

Description

Rewires graph to remove all 2-degree nodes. Nodes in the new graph will retain their original attributes. New edges will inherit attributes from the cominbation of their parent edges.

Usage

simplify_topology(graph, edge_attr_comb = list(.default.combiner =
  first), protected_nodes = NULL, progress = interactive())

Arguments

graph	An undirected igraph object
edge_attr_comb	Named list mapping edge attribute merging functions. See Details.
protected_nodes	Integer. Indices of nodes that should NOT be removed
progress	Boolean. Display progress bar?

Details

Specify this combination by providing a named list of summary functions. These summary functions must take a vector and return a scalar value of the same type. For example:

list(distance = sum, edge_id = max, .default.combiner = min)

The value of .default.combiner will be used for any edge attributes that aren't specified elsewhere in the list.

Value

An undirected igraph
