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.
P. S. See fortune(299).
