Thanks for the information. I reported the issue to the developers of
'igraph', which is where 'add_edges' comes from, here
The response there to the question of whether it is an R core or an
igraph issue was
R core for sure, but probably both.
Is this indeed the case for R core? To my naive eye, the error message
suggests more of a known limitation, rather than a bona fide bug.
