Matt,
  If you know that Y is a vector of length 4, why not try this.
Fakefunc(Y[1], Y[2], Y[3], Y[4], x5)

I'm sorry if my posting wasn't clear.
My real function is much more complicated.
I'm using the one I gave as a simplified example of my problem.

My intent was to find a way to convert (Y, x5)
to the same format as (x1, x2, x3, x4, x5).

So for example, the appropriate function call might look something like
           FakeFunc(unpaste(Y), x5)

That solution fails, but it gives you the flavor - I can't modify
the inside of the function at all.

Thanks,
Matt

Like this?

           FakeFunc<-function(Y, x5)
           {
                     sum(Y)+x5
           }

Is this what you mean?
