title: Comparison word cloud query
body: <p>I used the comparison.cloud function in wordcloud package in R. The word 'good' appeared in both Cat1 (27 times) and Cat2(33 times) categories however on the wordcloud it appears only under Cat1 for some reasons (probably because it is the first column).</p>
  
  <p>Can you suggest how can it be tweaked to get all the words (even though if it is same words in multiple categories). This is a significant finding for my dataset and it defeats the purpose of comparing the cloud when it deletes the most important word from Cat2.</p>
  
  <p>Data looks like this matrix:</p>
  
  <pre><code>       Cat1     Cat2     Cat3
  </code></pre>
  
  <p>good  ---    27 --------     33 ---------       3</p>
  
  <p>bad   ---    10 -----------     6    ---------       4</p>
  
  <p>...</p>
  
  <p>Code is:</p>
  
  <h1>comparison word cloud</h1>
  
  <p>tdm= read.table("doc.csv")</p>
  
  <p>png("comparision_wordcloud.png", width=1280,height=800)</p>
  
  <p>comparison.cloud(tdm, colors = brewer.pal(nemo, "Dark2"), use.r.layout=FALSE,</p>
  
  <pre><code>             scale = c(4,.5), max.words = 1000, rot.per=.1, random.order = FALSE, title.size = 2)
  </code></pre>
  
  <p>Let me know if this has a quick fix.</p>
