title: hclust() with cutree...how to plot the cutree() cluster in single hclust()
body: <p>I clustered my hclust() tree into several groups with cutree(). Now I want a function to hclust() the several groupmembers as a hclust()...
  ALSO:</p>
  
  <p>I cut one tree into 168 groups and I want 168 hclust() trees...
  My data is a 1600*1600 matrix. </p>
  
  <p>My data is tooooo big so I give you an example</p>
  
  <pre><code>m&lt;-matrix(1:1600,nrow=40)
  #m&lt;-as.matrix(m) // I know it isn't necessary here
  m_dist&lt;-as.dist(m,diag = FALSE )
  
  
  m_hclust&lt;-hclust(m_dist, method= "average")
  plot(m_hclust)
  
  groups&lt;- cutree(m_hclust, k=18)
  </code></pre>
  
  <p>Now I want to plot 18 trees... one tree for one group. I've tried a lot..  </p>
