problem with cor() using bigmemory
Hello, I have a rather large set of data I need to analyze, currently I need to work with a 200000 by 200000 matrix, I'm using the package bigmemory but so far I can only allocate a 66000 by 66000 matrix, when I increase those values I get the following error:

BigMatrix.cpp line 225
