title: Get all Parameters as List
body: <p>Does R provide an object/function/method/keyword to get all function arguments?</p>
  
  <p>Using an example:
  <code>function(a, b="default", ...)</code> would provide <code>a</code> and <code>b</code> as well as <code>...</code> within the function environment. Is there a statement similar to <code>list(...)</code> that would also include <code>a</code> and <code>b</code> in the result?</p>
  
  <p>Or put yet another way: a shorthand for <code>list(a=a, b=b, ...)</code>, given <code>function(a, b, ...)</code></p>
