title: How do I see the help for the `dplyr::collect` method?
body: <p>I am trying to find out what additional arguments can be passed to <code>dplyr::collect</code> in the ellipsis <code>...</code>. I want to do this because I believe that the behaviour of <code>collect</code> has changed between <code>dplyr</code> version <code>0.4.3</code> and <code>0.5</code>. It seems that in the new version <code>collect()</code> only downloads the first 100k rows, unless a new <code>n = Inf</code> argument is passed.</p>
  
  <p>I have retrieved the methods associated with <code>collect</code> using:</p>
  
  <pre><code>&gt; methods('collect')
  [1] collect.data.frame* collect.tbl_sql*   
  see '?methods' for accessing help and source code
  </code></pre>
  
  <p>I have looked at the help file for S3 <code>methods</code> but cannot work out how to get help on <code>collect.tbl_sql</code>, as <code>?"dplyr::collect.tbl_sql"</code> does not work.</p>
