title: How to update summary when using NeweyWest?
body: <p>I am using NeweyWest standard errors to correct my <code>lm() / dynlm()</code> output. E.g.:</p>
  
  <pre><code>fit1&lt;-dynlm(depvar~covariate1+covariate2)
  coeftest(fit1,vcov=NeweyWest)
  </code></pre>
  
  <p>Coefficients are displayed the way I´d like to, but unfortunately I loose all the regression output information like R squared, F-Test etc. that is displayed by summary. So I wonder how I can display robust se and all the other stuff in the same summary output. </p>
  
  <p>Is there a way to either get everything in one call or to overwrite the 'old' estimates?
  I bet I just missed something badly, but that is really relevant when sweaving the output.</p>
  
  <p>Test example, taken from <code>?dynlm</code>.</p>
  
  <pre><code>require(dynlm)
  require(sandwich)
  data("UKDriverDeaths", package = "datasets")
  uk &lt;- log10(UKDriverDeaths)
  dfm &lt;- dynlm(uk ~ L(uk, 1) + L(uk, 12))
  
  #shows R-squared, etc.
  summary(dfm)
  
  #no such information
  coeftest(dfm, vcov = NeweyWest)
  </code></pre>
  
  <p>btw.: same applies for <code>vcovHC</code>  </p>
