Hi Alain, You are probably storing the result, replicated five times, in df$VAR. Each cycle of the loop replaces the last value with the current value. If you really want the entire output of binom.test in the last column:
multi.binom.test<-function(xs,ns) { reslist<-list() for(i in 1:length(xs)) reslist[[i]]<-binom.test(xs[i],ns[i]) return(reslist) } df$VAR<-multi.binom.test(df$x,df$n) I suspect that you probably want only the p.value element.
