 Hi,

Im using R-2.8.1 on windows vista and have 4GB RAM. Im trying to run LDA
from the MASS package on a fairly large dataset and keep running out of
memory ("Cannot allocate vector of size ...)

Ive tried freeing up as much memory as possible with gc(). I tried using the
ff package but that would need modifications to the way LDA accesses the
memory mapped data. The error I get is "invalid 'type' (list) for variable
..."

Basically, I need someone's help on how I can force R to use the large
swaths of empty space on my hard drive as virtual memory. As I understand
it, virtual memory increases the address space. So, why isnt R capable of
using my hard drive. I dont mind the hit in performance. How do I get this
to work? And if I cant why cant I?

Any help would be sincerely appreciated.

Thanks in advance!
VG
