title: Critical Value for Shapiro Wilk test
body: <p>I am trying to get the critical W value for a Shapiro Wilk Test in R.</p>
  
  <pre><code>        Shapiro-Wilk normality test
  
  data:  samplematrix[, 1]
  W = 0.69661, p-value = 7.198e-09
  </code></pre>
  
  <p>With n=50 and alpha=.05, I know that the critical value W=.947, by conducting the critical value table. However, how do I get this critical value, using R?</p>
