[R] modifying the dots argument - how?

[Mark Heckmann]

Is there a way to modify the dots-argument?
Let's consider I have a function that passes on its ... arguments to  
another function.
For some reason I know, that some elements in ... will cause problems.
Can I modify the ... structure somehow, e.g. delete elements?

foo <- function(...){
	innerFoo <- function(...){
		
	}

	AT THIS POINT I WANT TO MODIFY THE CONTENT OF ... BEFORE IT IS PASSED  
ON

	innerFoo(...)
}

Thanks,
Mark
