title: Extract the names of rejected variables from step function
body: <p>I use step function on a glm object</p>
  
  <pre><code>stepglm&lt;-step(glmmodel)
  </code></pre>
  
  <p>and step rejects 2 variables from glmmodel. Is there a way to extract the names of the rejected variables from stepglm object? It seems that stepglm is just a glm object so perhaps there is no easy way to do this?</p>
