vertexDeleteReconnect: Network editing: removing vertices and connecting their...

In NetPathMiner: NetPathMiner for Biological Network Construction, Path Mining and Visualization

Description

This function removes vertices given as vids and connects their neighbours as long as the shortest path beween the neighbours are below the reconnect.threshold.

Usage

vertexDeleteReconnect(graph, vids, reconnect.threshold = vcount(graph),
  copy.attr = NULL)

Arguments

graph	A reaction network.
vids	Vertex ids to be removed.
reconnect.threshold	If the shortest path between vertices is larger than this threshold, they are not reconnected.
copy.attr	A function, or a list of functions, combine edge attributes. Edge attributes of new edges (between reconnected neighbours) are obtained by combining original edges attributes along the shortest path between reconnected neighbors.

Value

A modified graph.
