Yes, indeed, scary - since it means someone is killing R which means there is 
not much R itself can do about it. In fact from the syslog I see

May  4 20:48:11 ginaz kernel[0]: low swap: killing pid 56256 (R)

so it's the kernel's own defense mechanism. The bad thing is that R cannot do 
anything about it - the kernel just decides to snipe processes it thinks are 
dangerous to the health of the system, and it does so without a warning.

Cheers,
