title: ANOVA with differring variable length
body: <p>This code</p>
  <pre><code>x &lt;- runif(100,1,99)
  y &lt;- runif(75,1,99)
  
  aov(x ~ y)
  </code></pre>
  <p>Yields:</p>
  <pre><code>Error in model.frame.default(formula = x ~ y, drop.unused.levels = TRUE) : 
    variable lengths differ (found for 'y')
  </code></pre>
  <p>How can I run an ANOVA on variables with differing length?</p>
  <p>I know this is asked in one form or another elsewhere, but never this simple. I feel this will help a lot of people trying to understand this concept.</p>
