title: Can someone explain the output from the pvclust function in R?
body: <p>In the <code>pvclust</code> package in R, there is the <code>pvclust()</code> function. In the example provided in the function help file, there's the function:</p>
  
  <pre><code>boston.pp &lt;- pvpick(boston.pv)
  </code></pre>
  
  <p>This is supposed to print out the clusters with high p-values. The output of this function is:</p>
  
  <pre><code>$clusters
  $clusters[[1]]
  [1] "rm"   "medv"
  
  $clusters[[2]]
  [1] "zn"  "dis"
  
  $clusters[[3]]
  [1] "crim"    "indus"   "nox"     "age"     "rad"     "tax"     "ptratio" "lstat"  
  
  
  $edges
  [1] 3 5 9
  </code></pre>
  
  <p>I have a lot of trouble understanding what the output means, especially since I have very limited technical background on cluster analysis. In particular, I don't understand the meaning of the vector of names under each cluster. Can someone explain this for me? Thanks!</p>
