I am new to R,so excuse me if its too basic. I have a vector of scores
S= {s1,s2,s3,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,sn}
n could be very large.
I want to find p-value for each score and I have the formula
pvalue= 1-exp(-exp(S))
so any ideas how to get this new vector P={p1,p2,p3,p4,p5....pn}
thankyou in advance

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 On 06/08/05, Rangesh Kunnavakkam <rangeshk at gmail.com> wrote:> I am new to R,so excuse me if its too basic.
