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