find_path: Constructs a path from a matrix of edge weights.

In PairViz: Visualization using Graph Traversal

Constructs a path from a matrix of edge weights.

Description

Returns a path, constructed by applying the function in path to the edge weights. If each edge has many weights, i.e if edgew is a matrix, these weights are first reduced by the function combine applied to the rows. If path is NULL, the returned path defaults to 1..nnodes(edgew)

Usage

find_path(edgew, path=NULL,  combine=sum, edge.index=edge_index(edgew),...)

Arguments

edgew	Matrix (or vector) whose ith row (or element) has weights for pair indexed by pair in row i of edge.index.
path	a function used to construct the index path.
combine	A function that combines the row of weights for an edge into a single numeric value.
edge.index	A 2-column matrix with each row giving indices for corresponding weight in edgew.
...	passed to path construction function.
