Re: [igraph] Union of two directed graphs in R

[Matt Rissler]

But looking at the source, the comment distinctly states that that directed are not allowed?  Does this work in Python?  If so, back to SAGE for this project.

Thanks again.

I'm trying to union two directed graphs by name and I get the following error.

graph.union.by.name(AAD,ACC)

Error: !is.directed(g1) & !is.directed(g2) is not TRUE

The documentation intimates that this should work.  Does the check need to be changed to a not xor.

Thanks,

Matt
