  <p>I have just one column full of names, and I need to know how many times each name is on this column.</p>
  
  <p>I can do a </p>
  
  <pre><code>summary(dfUL)
  </code></pre>
  
  <p>where dfUL is my user list data frame</p>
  
  <p>This will give me a summary with the number of times a particular value is repeated, but it will only do it for the top 6. How can i do that for the entire data frame?</p>
