Just rename the file to `fix_dendrogram.py` after downloading it; the mailing list server incorrectly assumes that it is a binary file but it isn't.

cl is an incomplete (partial) dendrogram returned by some of the low-level C functions in igraph. The Dendrogram class requires a full dendrogram; fix_dendrogram() merges the multiple roots of the...

The issue should not have been closed in the first place, thanks for letting me know. The `fix_dendrogram()` function is a crude hack only; basically, when you give it an...

Well, it could be - the `fix_dendrogram()` function I posted to the mailing list was a temporary solution only for the question of that particular user, and I did not...

This is going to be more complicated than it seems; essentially we need to end up plotting a _different_ graph and not what the user really wants to plot, and...

_From @tintinthong on September 21, 2017 4:15_ I was looking at the graph.bfs code and the naming issue of father becomes a problem after `.Call(C_R_igraph_bfs, graph, root, roots, neimode, unreachable,...

_From @tintinthong on September 21, 2017 5:35_ So although I see that the problem may be due to internals. It usually has to do with the naming of vertices. If...

igraph vertices always have numeric IDs from 1 to the number of vertices, inclusive (at least in R; in C or Python, the vertex IDs are zero-based). When you use...

_From @tintinthong on September 21, 2017 8:10_ This is what I obtain. I am unsure if the output is the named output or the some index(perhaps index of the vertex...

I think this is a bug in the printing routine corresponding to `obj`; the raw content of `obj$father` _before_ the vertex names are resolved is correct (irrelevant parts omitted): ```...
