The question is even more pressing for me now given that I no longer can convert some csr matrices to the regular ones for scaling. (http://article.gmane.org/gmane.comp.lang.r.general:279305) Any suggestions? (the original csr matrix is too large to be converted to a regular one, but the product is small enough).
