R help - May 2008 - SVD for a 500, 000* 500, 000 matrix (singular value decomposition)

Hi,


I tried to run SVD on a  500,000* 500,000 matrix and i get a message that it
can  not allocate a vector of length 270 mb

Well, you will obviously need >> 1Tera(!)bytes of RAM just in order to 
store the matrix (or is it some sparse one?). I wonder how you managed 
that issue.
