k_shortest_paths | R Documentation |
k
shortest paths between two verticesFinds the k
shortest paths between the given source and target
vertex in order of increasing length. Currently this function uses
Yen's algorithm.

graph |
The input graph. |
from |
The source vertex of the shortest paths. |
to |
The target vertex of the shortest paths. |

These dots are for future extensions and must be empty. |
k |
The number of paths to find. They will be returned in order of increasing length. |
weights |
Possibly a numeric vector giving edge weights. If this is

mode |
Character constant, gives whether the shortest paths to or from
the given vertices should be calculated for directed graphs. If |
A named list with two components is returned:
