You say you're on a 64-bit box, but are you running 64-bit R?

Hi all, I'm having great trouble working with the Cforest (from the party package) and Random forest functions. Large data set seem to create very large model objects which means I cannot work with the number of observations I need to, despite running on a large 8GB 64-bit box. I would like the object to only hold the trees themselves as I intend to export them out of R. Is there anyway, either through options or editing out code and recompiling them, I can reduce their footprint? I've had a look at the cforest code and the culprit is the 'emsemble' area of the object. I suspect this part of the object contains something related to the number of observations (I have savesplitstats set to FALSE so this shouldn't be the issue). Thanks, Matt
