title: Cluster Analysis using pvclust in R
body: <p>I want to do cluster analysis of certain columns (variables), say var 5-var10. For that I used <code>pvclust</code> in R. Now, I want to add this column of clusters into the actual dataframe. Can anybody please help me to fix this problem. The code I used is given below:</p>
  
  <pre><code>group &lt;- sqldf("select cq14x1_1,cq14x1_2,cq14x1_3,cq14x1_4,cq14x1_5,cq14x1_6,cq14x1_7, from parma_1")
  fit_1 &lt;- pvclust(group,method.hclust="ward",method.dist="euclidean")
  group_2 &lt;- (fit_1,alpha=.90)
  </code></pre>
