I seem Unable to allocate arrays of size > around 2GB in 64 bit Windows 7 R. There is a lot of main memory available. The memory.limit is set to the max memory available, and there is more than 10GB of that available when R returns an 'unable to allocate memory' error. Is this a limitation of R even in 64 bit Windows 7? Or is there a wY to get I've this?
There's currently a limit of 2^31-1 in the length of a vector in all versions, so that's the most entries you can have in a matrix as well.
The data in each entry is usually more than one byte, so the total size of allocation can be much bigger than 2 GB, but the number of entries can't.
