The natural way will depend on what you're trying to do, and since you 
don't give us a reproducible example as the posting guide asks for, we 
can only guess.

There are for loops.
There are the apply series of functions. (?apply, ?lappy, ?mapply, etc.)
There is ?replicate.

You also might avoid having to call your function multiple times 
completely if you vectorize it.
