Even when it does start using virtual memory (which you never want it to do from a performance standpoint), there is still the physical limitation (e.g., a 2-3GB on Windows depending on how you have it configured) that you can not exceed. Also the maximum memory is set to:
--max-mem-size=N (Windows only) Specify a limit for the amount of memory to be used both for R objects and working areas. This is set by default to the smaller of 1.5Gb24 and the amount of physical RAM in the machine, and must be between 32Mb and 3Gb. This is a parameter on the startup command. On my machine I have 2GB and let it default to 1.5GB. This number should be less than the physical memory on your system. This is what is "runs out of".
