Hi, I want to compute p value of sign test for sample size=15 from normal distr., sd=0.5, mean=1, alternative should be two sided. Is this code correct in this situation? binom.test(sum(rnorm(15,1,0.5)>0),15,p=0.5,alternative="two")$p.value Or should I use another code (function) e.g. rbinom? Thank you very much. kind regards, T. Bal [[alternative HTML version deleted]]

I'm looking for a way of vectorising a "running balance"; i.e. the value in the first row of the dataframe is zero, and following rows add to this running balance. This is easy to write in a loop, but I can't seem to get it working in
