title: R function definition in Visual Studio v.s. R Gui
body: <p>When I write function name without parenthesis in R Gui (e.g. <code>library</code>) I see the complete function definition (several pages of code); in Visual Studio 2017 environment I see only the following:</p>
  
  <pre><code>function (...) 
  {
      if (nargs() == 0) {
      invisible(rtvs:::send_notification("!Library"))
  }
  else {
      base::library(...)
      }
  }
  &lt;environment: namespace:rtvs&gt;
  </code></pre>
  
  <p>Why Visual Studio shows abbreviated version? Are they equivalent? How can I get the complete function?</p>
