error: "as(<dsCMatrix>, "dgCMatrix") is deprecated ... "

Hi!

After updating the Matrix package to v1.5-1, calling igraph::as_adjacency_matrix() throws the message
as(<dsCMatrix>, "dgCMatrix") is deprecated since Matrix 1.5-0; do as(., "generalMatrix") instead.

as(<dsCMatrix>, "dgCMatrix") is called within the igraph-internal function get.adjacency.sparse().

Best,
Stefanie

This is fixed in the recently released igraph 1.3.5:

> as_adjacency_matrix(sample_gnm(4,4))
4 x 4 sparse Matrix of class "dgCMatrix"
            
[1,] . 1 1 1
[2,] 1 . 1 .
[3,] 1 1 . .
[4,] 1 . . .

Please double-check that this is the version you are using, and if you still see problems, please post a minimum reproducible example.
