Hi, Before someone gives professional advice, you may do an experiment: Set the windows virtual memeory to be as large as ~128GB, (make sure the hard drive has enough space, restart might be required); increase the memroy limit in R; load a big dataset (or iteratively assign it to an object, and do some calculation.....Definitely will be very slow) I am not sure. Just try to help.
