title: Argument of set.seed in R
body: <p>I am trying to understand how <code>set.seed</code> works in R. I understand it, can reproduce random samples, but I don't know what is the difference between <code>set.seed(1)</code> and <code>set.seed(123)</code> ?</p>
  
  <p>What do the argument in the bracket mean ?  </p>
