Re: [igraph] working with bipartite graphs

[Gábor Csárdi]

Hi,

unfortunately getting only one projection is not supported. It was already requested before:

https://github.com/igraph/igraph/issues/307

I will code it up at some point, but probably not very soon. You can try modifying the C code of igraph, or just write the function for yourself, it is probably not very hard, and you could use graph.neighborhood to get the second neighbors of the type-1 nodes.

Hi,

I'm also experiencing memory limitations on my pc for the projection of a bipartite network.

Is it possible to choose only one projection (in this case, the first one, hopefully the one I want to look at) ?

$vcount1

$ecount1

$vcount2

$ecount2

Thank you for your answer.

Sincerly
