title: Remove names from named vector and get only the values
body: <p>I have a vector like below</p>
  
  <pre><code>tmp &lt;- c(a=1, b=2, c=3)
  </code></pre>
  
  <blockquote>
    <p>a b c<br>
    1 2 3</p>
  </blockquote>
  
  <p>I want to flatten this vector to get only <code>1, 2, 3</code>.</p>
  
  <p>I tried <code>unlist(tmp)</code> but it still gives me the same result. </p>
  
  <p>How to achieve that efficiently?</p>
