  </code></pre>
  
  <p>Whole CSV (<a href="https://github.com/antonio1695/BaseX/blob/master/facturas1.csv" rel="nofollow">https://github.com/antonio1695/BaseX/blob/master/facturas1.csv</a>)
  To download the file just click on find file and then you will see the file. 
  So what I did was:</p>
  
  <pre><code>&gt; df1 &lt;- read.csv("facturas1.csv")
  &gt; rules &lt;- apriori(df1,parameter=list(support=0.01,confidence=0.5))
  Error in asMethod(object) : 
  column(s) 3 not logical or a factor. Discretize the columns first.
  </code></pre>
  
  <p>Nevertheless, the problem is that the columns are discrete already and if I change the data in order for it to have column 3 in the place of column 2 and viceversa. It still says that that column 3 is not logical or a factor when it should say it about column 2 instead. Thanks! </p>
