title: Is there any way to find the summary of a vector in R without using any inbuilt function or any kind of loop..just operations between vectors?
body: <pre><code>x&lt;-rnorm(100)
  </code></pre>
  
  <p>i want to find the summary of x for example without using inbuilt functions like <code>sum()</code> <br>
  or any kind of loops like (for,while,repeat...) <br>
  Is there a way to do that?</p>
