Re: [igraph] Function 'neighborhood' for non-integer distance

[Gábor Csárdi]

Hi!

The neighborhood functions do not take edge weights into account,
unfortunately.
Their terminology is also unfortunate, they should say 'hops' instead
of 'distance'.

You may open an issue in the GitHub issue tracker and make a case for
this feature.
