Greetings,

I have been playing around with the R/Parallel package, which can farm out the computation of a for-loop among multiple worker processes.  Each worker gets a chunk of the for-loop iterations; for example, if you have two workers and for(x in 1:1000){...}, one worker would typically get iterations 1:500, while the second does 501:1000.

I would like to be able to preallocate matrices to capture the results within the for loop, on the first iteration.  Is there a way to access the list argument of the "for" function programmatically from within the loop?  I am referring to the for arguments shown on page 51 of the R Language Definition manual:

   "for"(var,list,expr)

I think I have a work-around, but was curious whether this was possible...

Thanks,
Mike
