title: Why ets() function in R is not fitting a seasonal model?
body: <p>I am using <code>ets()</code> function in R to fit the seasonal model.I have a weekly sales data.I can see clearly in my data that it has seasonal patterns along with trend. Following is the code:</p>
  
  <p><code>x_ts&lt;-ts(x,frequency=52,start=c(1,1))</code></p>
  
  <p><code>nfit &lt;- ets(x_ts,damped=FALSE)</code></p>
  
  <p>Is it because I have used damped=FALSE in my model?
  I would appreciate any kind of help/suggestion.</p>
