title: How do I apply the same filter to 50+ data frames?
body: <p>I have about 50 unique data frames with the same column names. </p>
  
  <p>Right now I have something like this:</p>
  
  <pre><code>df1_cleaned &lt;- df1$price
  df1_cleaned &lt;- df1$date 
  df2_cleaned &lt;- df2$price
  df2_cleaned &lt;- df2$date
  ...
  </code></pre>
  
  <p>There are 10 columns in the uncleaned data frames, I'm only interested in getting the 3rd and 5th columns of each.</p>
  
  <p>Is there a way to do this without writing out every single data frame?</p>
  
  <p>Cheers</p>
