[R] R process gets killed spontaneously

Hi Peng,

in a very simplistic manner, what happens is that the Operating System  
"thinks" it is too dangerous to let the R process to use so much  
memory. So, to protect the whole system, it kills R, before the system  
becomes unstable.

I've been looking at the problem you observed last week and, as I  
promised, I will come back to you with my findings sometime this week.  
I was already informed on how to reduce the memory footprint when  
creating the specific object you're interested in, but still need to  
run some tests.

Will get back to you soon,
