title: Collecting all function arguments in R
body: <p>Naively, I thought that R's ... notation would collect all named arguments that appear after it so that they can be passed along. For example:</p>
  
  <pre><code>&gt; a &lt;- function(..., arg=TRUE) b(...)
  &gt; b &lt;- function(arg=TRUE) print(arg)
  &gt; a(arg=FALSE)
  [1] TRUE # I would want this to be FALSE
  </code></pre>
  
  <p>Since this clearly doesn't happen, is there some way to package up all of the arguments supplied to a function so that they get sent along? </p>
