title: Put Autoarima summary results in data frame R
body: <p>I am running several regression models and desire to have the results in a data frame. I tried several methods they have been unsuccessful.</p>
  
  <pre><code>Series &lt;- ts(DATA[,2],start = c(2012,9), end = c(2019,6),frequency = 12)
  model1 &lt;- auto.arima(Series)
  </code></pre>
  
  <p>The result is:</p>
  
  <pre><code>Series: Series 
  ARIMA(3,0,0)(0,1,1)[12] with drift 
  
  Coefficients:
           ar1     ar2     ar3     sma1   drift
        0.4960  0.0948  0.2315  -0.7907  -1e-04
  s.e.  0.1279  0.1377  0.1330   0.3010   2e-04
  
  sigma^2 estimated as 6.651e-06:  log likelihood=314.61
  AIC=-617.22   AICc=-615.89   BIC=-603.73
  </code></pre>
  
  <p>I am using this code:</p>
  
  <pre><code>A &lt;- data.frame(unclass(summary(model1)), check.names = FALSE, stringsAsFactors = FALSE)
  </code></pre>
  
  <p>I only get:</p>
