title: error message in R when using samr
body: <p>I have been using SAM(Significance analysis of microarrays) in R, when my program runs it got halted when performing the operations using the sam instruction. The messages that displays are:</p>
  
  <pre><code>Cluster size 12488 broken into 6032 6456 
  Cluster size 6032 broken into 2628 3404 
  Cluster size 2628 broken into 1051 1577
  </code></pre>
  
  <p>In some datasets it appears those messages, but the processing continues without no problem at all; while in others the program hangs. R does not display any message, but the one that displays those messsages of Cluster broken is Rstudio.</p>
  
  <p>The sam instruction that I am using is something like:</p>
  
  <pre><code>samfit &lt;- SAM(t, numbas, resp.type="Two class unpaired",
                           nperms=100, 
                           testStatistic=c("standard"),
                           knn.neighbor=10, 
                           random.seed=1234567, 
                           logged2=TRUE,
                           genenames=rownames(t))
  </code></pre>
  
  <p>Does anybody came with that error before maybe without using sam for R? I have made a search in google, but I have not found anything about it</p>
  
  <p>Thanks</p>
