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.

Thank you very much for any help.
