title: Predict function in forecast.holtwinters function
body: <p>I am looking at <code>forecast</code> package <code>HoltWinters</code> method code from <a href="https://github.com/robjhyndman/forecast/blob/master/R/forecast2.R" rel="nofollow">this link</a> (for code understanding purpose). I couldn't find which "R" source file has this <code>predict</code> function defined in to look at source code. Can some one please help me on how can trace this function to a specific source code file?</p>
  
  <pre><code> pred &lt;- predict(object,n.ahead=h,prediction.interval=TRUE,level=level[1]/100)
  </code></pre>
  
  <p>Any help would be appreciated.</p>
