using a standard dataset from R?
But, you could first try to use compiler package, see ?enableJIT.
Another option would be to use doMC/foreach packages if you can run

I cannot run your code because not all the variables are defined, but

in the loop. Instead, pull out masskg as a new stand-along object
before the start of the loop and put it back into rftab at the end of
the loop. E.g., someth
