removeEdge
A function to remove the specified edges from a graph.
removeEdge(from, to, graph)
from |
from edge labels |
to |
to edge labels |
graph |
a |
A new graph instance is returned with the edges specified by
corresponding elements of the from and to vectors
removed. If from and to are not the same length, one of
them should have length one. All edges to be removed must exist in
graph.
A new instance of a graph with the same class as graph is
returned with the specified edges removed.
