title: r get value only from quantile() function
body: <p>I'm sorry for what may be a silly question.
  When I do:</p>
  
  <pre><code>&gt; quantile(df$column, .75) #get 3rd quartile
  </code></pre>
  
  <p>I get something like</p>
  
  <pre><code>75% 
  1234.5 
  </code></pre>
  
  <p>Is there a way to just get the value (1234.5) without the descriptive "75%" string? Thank you very much.</p>
