title: R syntax for selecting all but two first rows
body: <p>How do I select all but the first two rows from e.g. the mtcars dataset?</p>
  
  <p>I know that I can write <code>no_mazda &lt;- mtcars[3:32]</code>, which does work as long as I know the number of rows. But when I don't know the number of rows I need to write e.g. <code>no_mazda &lt;- mtcars[3:nrow(mtcars)]</code> which of cause also works, but:</p>
  
  <p>Does R provide a smarter syntax than an expression that includes <code>mtcars</code> twice?</p>
