Adjacency to transposed edgelist in igraph in R

I have a relatively large 2 mode network in adjacency matrix form of 4000 rows and 9000 columns I'm interested in looking at the relationships between the columns.

With a smaller network I would do t(matrix) %*% matrix, however I think a 9000^2 matrix would max out the memory on my computer.

One option is to convert the igraph adjacency matrix to the sna pacakge format, and use sna::gt, but I was wondering if there was similar functionality in igraph?

Thanks,

Use graph.incidence to construct the bipartite graph from your adjacency matrix, and then use bipartite.projection to project it to the corresponding one-mode network, based on either the rows or the columns.
