title: R 1000 rnorm samples
body: <p>x &lt;- rnorm(25)  will produce a single sample of size 25 from the standard normal distribution.</p>
  
  <p>How do I take 1000 samples of size 25 from standard normal distribution at the same time?</p>
  
  <p>I would like to do this efficiently, so that I will be able to compute things such as the mean and standard deviation for each of the 1000 samples and compare them via a histogram.</p>
  
  <p>[Also: I would then like to uniformally and randomly select one of these 1000 samples and bootstrap it]</p>
