Dear all, I have a .dta database which is about 400 MB. I cannot open it though I have no problem to import smaller ones (80 MB or even 174 MB). I tried to modify some options with --max-mem-size=2047M --max-vsize=2047M. But it does not seem to be enough. I do not know the exact meaning of these options : vsize seems to be made for vectors.
See ?Memory on memory handling in R.
I have got Monte Carlo simulations running in another R window. Can MCMC simulations take enough memory so as to prevent me from opening this database ?
Amount of RAM used by the MCMC simulations? If no (not even virtual) RAM is left: of course they can prevent. Uwe Ligges
Thank you very much for any help. Best Regards [[alternative HTML version deleted]]
