Hi,all!

I encountered a problem "not-yet-implemented method for <list> %*%
<dgCMatrix>" when I tried "diagr %*% design_mat", where
"diagr<-diag(vr,100)", vr is a vector with 100 elements, and design_mat is a
sparse matrix with dimension 100*677000 constructed by calling
sparseMatrix().

I am new to the Matrix package, so I am confused with this, and I need your
help~~
Thanks!

best regards!
June
