title: percent_rank function in dplyr
body: <p>I'm trying to use the percent_rank function in dplyr to divide one of my variables to into 3 separate variables depending on where they fall in the percent rank. I have the dplyr function loaded but the console keeps telling me that it can't find the function.</p>
  
  <p>My code looks like this:</p>
  
  <pre><code> library(dplyr)
   high_val &lt;- percent_rank(df$val1) &lt;- 0.66
  </code></pre>
  
  <p>And then continues on for each variable I want to divide. 0.66 is the percentile for the high value I want to use (66%). Any ideas?</p>
