title: Error in dimnames(res) of MCA (FactoMineR)
body: <p>i am doing MCA with FactoMineR but always have the same error message!</p>
  
  <p>This is my data <code>valqualis</code> to be analysed. 156 rows and 20 columns.</p>
  
  <pre><code>P1 20 4.708846 111  11 0011 0010 11  1 1 1 0 1 1 1 1 1 1 1 1
  P1 3  4.790977 10NA 10 0111 0001 0NA 1 1 0 1 1 1 1 1 1 1 0 0 
  </code></pre>
  
  <p>And this is the code I am doing to run it.</p>
  
  <pre><code>require(FactoMineR)
  require(factoextra)
  
  #ACM
  res.mca&lt;-MCA(valqualis) 
  </code></pre>
  
  <p>But each time I have the following error:</p>
  
  <p><code>Error in dimnames(res) &lt;- list(attributes(tab)$row.names, listModa) : 
    length of 'dimnames' [2] not equal to array extent</code></p>
  
  <p>Any ideas?</p>
