Description

Determines if a trek system exists in the mixed graph.

Usage

## S3 method for class 'MixedGraphFixedOrder'
getTrekSystem(this, fromNodes, toNodes,
  avoidEdgesOnRight = NULL)

## S3 method for class 'MixedGraph'
getTrekSystem(this, fromNodes, toNodes,
  avoidEdgesOnRight = NULL)

Arguments

this	the mixed graph object
fromNodes	the start nodes
toNodes	the end nodes
avoidEdgesOnRight	a collection of edges in the graph that should not be used on any right hand side of any trek in the trek system.
