title: Haplotype Network with haploNet show labels with "2" and overlapping circles in R
body: <p>I'm working in R. From a dataset of about 150 sequences I want to draw an haplotype network.</p>
  
  <p>I used haploNet function in the "pegas" library. The problem is that I obtain a network with a lot of "2" labels (labels within a grey square indicating 2). I don't know exactly what is it.</p>
  
  <p>In addition I have several overlapping circles.</p>
  
  <p>Do you have any suggestions?</p>
