Hi,all!
after executing :
library(Matrix)
spr_mat<-sparseMatrix(mydataframe$r,mydataframe$c,x=mydataframe$v)
diagr<- diag(vr,nrow=ins_num)
A<-diagr%*%spr_mat
I encountered a error "not-yet-implemented method for <list> %*%
<dgCMatrix>"
could someone show me some tips?
many hanks!
best regards!
June
