Hi, everyone:
     R is new to me. I am writing a nested loop to simulate data for t-test. The following code is wrong. The subscript is out of bounds. Could anyone tell me how to revise it? Thanks, Riddle Chin.
   
  result<-matrix(ncol=5, nrow=1000)
colnames(result)<-c('N=20','N=40','N=60','N=80','N=100')
 for (i in 1:1000){
   for (j in seq(20,100,20)){
     x<-rnorm(j,2.7,1)
     result[i,j]<-t.test(x,mu=4)$p.value<=0.05
   }
 }
