Is there a way to force a hard RAM-usage limit for R, resulting in it using swap space after it is hit?

Question

There is a memory-management process on a server I use that kills processes that go above a certain limit.

There are very large data files that must be loaded in their entirety, but doing so goes above the memory limit.

Is there a way to force R to limit the amount of memory on RAM and use swap-space/a swapfile after it is hit?
