Re: [igraph] Retrieve nodes forming a motif with subgraph_isomorphisms

[Phil Cui]

I compare ego with neighbors through system.time() and it turned out that ego was faster, but it may be just based on the couple of examples I tested.

No, I didn't copy the whole graph. Actually, the R code is almost the same as the Python one.

Are you sure about that? I would think that ego() is slower.

Also, I see no significant difference between the Python and R parts
that you have posted - could it be the case that the difference lies
elsewhere? For instance, could it happen that you accidentally "copy"
a graph or a large subset of it in the R code that you don't do in
Python?
