> Hi everyone,
> I recently ran a simulation on a computer using R that was hooked up to a UPS.  There was one time when the power was out for length and the computer shut down.  I was worried that I had lost the simulation, but upon booting the machine up, I heard the processor kick in.  It sounded like the simulation had resumed.

write your results, let's say every hour or 30' on your disk.
something like
if (substr(date(),...)=='30') write.table(...)
where it could take place
