Difference between mean and fitted in forecast function
<p>I'm new to forecasting and I'm trying to use the forecast package in r.  </p>

<p>Can someone please explain the difference between mean and fitted in the forecast function?</p>

<p>For example,</p>

<pre><code>fcast&lt;-forecast(ts,h=30)

fcast$mean

fcast$fitted
</code></pre>

<p>The documentation says "mean is Point forecasts as a time series" 
and "fitted is Fitted values (one-step forecasts)".  </p>

<p>An example to illustrate the difference would be great.  Any help much appreciated.</p>
