Would it be possible that on the Options Panel an option is included which allows to increase the paging file virtual memory on the computer.

This would allow the R Process to use more memory that the RAM memory available in the PC and benefit from the hard drive store space eg. The main visible advantage of this scheme is that programs can be larger than physical memory.
