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).
