title: scatter plot of binary and continuous variable
body: <p>I want to see the scatter plot of barrier score (binary variable) and age (a continuous variable). I want to convert my barrier score to continuous. </p>
  
  <ol>
  <li>I used the command <code>collapse (mean) barrierscore, by (Age)</code></li>
  <li>I renamed <code>barrierscore</code> by <code>rename barrierscore prbarrierscore</code></li>
  <li>Next I use the command <code>generate logit barrierscore1=ln(prbarrierscore/(1-prbarrierscore))</code></li>
  </ol>
  
  <p>The problem is that I am receiving the error message:</p>
  
  <blockquote>
    <p>too many variables specified</p>
    
    <p>r(103);</p>
  </blockquote>
  
  <p>Am I making a mistake with the commands?</p>
