title: In R, what is the default link function used when using the glm function with binomial family
body: <p>For instance, if I have the equation </p>
  
  <pre><code>glm(resp~var, family=binomial)
  </code></pre>
  
  <p>Is this the same as</p>
  
  <pre><code>glm(resp~var, family=binomial(link=logit))
  </code></pre>
  
  <p>Or does it use a different link as default?</p>
