title: Node labels on circular phylogenetic tree
body: <p>I am trying to create circular phylogenetic tree. I have this part of code:</p>
  
  <pre><code>fit&lt;- hclust(dist(Data[,-4]), method = "complete", members = NULL)
  
  nclus= 3
  color=c('red','blue','green')
  color_list=rep(color,nclus/length(color))
  clus=cutree(fit,nclus)
  
  plot(as.phylo(fit),type='fan',tip.color=color_list[clus],label.offset=0.2,no.margin=TRUE, cex=0.70, show.node.label = TRUE)
  </code></pre>
  
  <p>And this is result:

  <p>Also I am trying to show label for each node and to color branches. Any suggestion how to do that?</p>
  
  <p>Thanks!</p>
