title: Krippendorff's Alpha using R - Error in sort.list(y) : 'x' must be atomic for 'sort.list' Have you called 'sort' on a list?
body: <p>I'm trying to compute the inter-rater reliability between 3 raters and I have 7100 rows of data. So for example each row is like this:
  5,4,3</p>
  
  <pre><code>&gt; data &lt;- read.csv("/home/xyz/Desktop/tc.csv", header=TRUE)
  &gt; library(irr)
  Loading required package: lpSolve
  &gt; kripp.alpha(data, method="ordinal")
  Error in sort.list(y) : 'x' must be atomic for 'sort.list'
  Have you called 'sort' on a list?
  </code></pre>
  
  <p>How do I fix this?</p>
