Hi, 

I saw a discussion about this, but i couldn't make it work.

Sugestion:

"In out_deg, the first n1 values should be the
degrees of the vertices in the first bucket, the next n2 values will
be zero. In in_deg, the first n1 values will be zero, the next n2
values will be the degrees of the vertices in the second bucket."

I tried this in R:

g <- degree.sequence.game(out.deg = c(3, 2, 0, 0, 0, 0), in.deg = c(0, 0, 1, 1, 2, 1))

but the result is not a bipartite graph.

Why not? All the edges go between {1,2} and {3,4,5,6}, right? So this is a bipartite graph. 

If you mean that the graph has no 'type' argument, yes, you need to add that yourself, degree.sequence.game() does not know that it is generating a bipartite graph. You also might want to convert the graph to undirected.

What am I doing wrong?

Best, 

Caio
