[R] help regarding functions loops

Hi Rangesh, Perhaps I mis-understand your question, but it could be as simple as... p - 1-exp(-exp(s)) In R, this is vectorized such that a new vector is calculated - one value for each value of s, so p will have the same length as s. In the Introduction to R read up on vectors and how to
