Hi Abby, if you have questions about qaptest, then please post to the sna mailing list, this function is not part of igraph, and we have no idea how it works. 

Btw. if you don't want a sparse matrix, but a simple R matrix that sna can handle, then use get.adjacency(..., sparse=FALSE).

Thank you Tam and Gabor for your help with qaptest.  I was able to convert it to an adjacency matrix using get.adjacency(), however, it drops  the alter tie descriptors, which I need for the quadratic assignment procedure.  The result is a 3020*3020 matrix of class "dgCMatrix".  In my original dataset, I had 3020 individuals,  but I also had 26 tie attributes which I was going to use for the qap hypothesis testing procedure.  Do you know what format the procedure needs the data to be in in order to test the correlation between two types of alter connections with qap?

Thanks,
Abby
