[R] help regarding functions & loops

[Sean O'Riordain]

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 avoid loops.

cheers!
Sean
