You're correct, your question is not related to R.

But the answer (short, long or indifferent) to your question is No.

And furthermore, don't be silly.  SE = s/sqrt(n).  If you knew s you 
could solve for n, but you don't.  Full stop.  There's an end to it.
Any further mucking about is unproductive wishful thinking.
