title: Error - 'x' and 'y' must have the same length
body: <p>I am very new to coding and working on a Homework assignment for class.<br />
  This is the code and error I am getting:</p>
  <p>Code:</p>
  <pre><code>cor.test(HR_comma_sep$average_monthly_hours , HR_comma_sep$number_project , conf.level = .99)
  </code></pre>
  <p>Error:</p>
  <pre><code>Error in cor.test.default(HR_comma_sep$average_monthly_hours, HR_comma_sep$number_project, : 'x' and 'y' must have the same length
  </code></pre>
  <p>Any help would be appreciated...keep in mind I am new to this so an answer in layman's terms would help.  If you speak code to me I probably won't understand. :)</p>
  <p>Thank you in advance for your help.</p>
