title: test statistic for Spearman rank correlation
body: <p>my problem is that I have calculated Spearman rank correlations between two variables. One reviewer asked me if I could add also test statistics for all coefficients where p &lt; 0.001.</p>
  
  <p>Here is one result:</p>
  
  <pre><code>&gt; cor.test(pl$data, pl$rang, method= "spearman")
  
  
  #       Spearman's rank correlation rho
  
  data:  pl$data and pl$rang
  S = 911164.6, p-value = 1.513e-05
  alternative hypothesis: true rho is not equal to 0 
  sample estimates:
  rho 
  -0.3347658 
  </code></pre>
  
  <p>Is the test statistics equal to <strong>S = 911164.6</strong>? Is it OK that it is so big number?
  Sorry in advance if the question is not very professional but I spend quite some time searching for the answers in the books and on internet. :(
  Thank you for the help in advance.</p>
