[R] looping problem

[Roslina Zakaria]

Dear r-expert,
I would like to generate 30 sets of random numbers from uniform distribution (0,1). Each set of random numbers should have 90 data.  Here is my code:
rand.no <- function(n,itr)
{ for (i in 1:itr)
  {rand.1 <- runif(n,0,1)
  if (i ==1) rand.2 <- rand.1
  else rand.2 <- cbind(rand.2,rand.1)
  }
  rand.2
}
Question: The code is okay is just that it give me 31 sets instead of 30 sets. Can anybody any adjustment to my code.
Your help is really appreciated.
Thank you.
