[igraph] Help!!!how to get the laplacian of a huge graph with more than 10000 nodes?

[lan gao]

I have a large graph with more than 100000 nodes.

When I use graph.laplacian(g) , R says "can not locate a vecotor of size..."

If I save the graph in a sparse matrix form, then is not the right graph object that "graph.laplacian" requires.

What can I do?

Anybody knows how to sovles this problem? I appreciate your help.
