title: How to visualize a list of lists of lists of ... in R?
body: <p>I have a very deep list of lists in R. Now I want to print this list to the standard output to get a better overview of the elements. It should look like the way the StatET plugin for eclipse shows a list. <br>
  Example list:</p>
  
  <pre><code>l6 = list()
  l6[["h"]] = "one entry"
  l6[["g"]] = "nice"
  l5 = list()
  l5[["e"]] = l6
  l4 = list()
  l4[["f"]] = "test"
  l4[["d"]] = l5
  l3 = list()
  l3[["c"]] = l4
  l2 = list()
  l2[["b"]] = l3
  l1 = list()
  l1[["a"]] = l2
  </code></pre>
  
  <p>This should print like:</p>
  
  <pre><code>List of 1
   $ a:List of 1
    ..$ b:List of 1
    .. ..$ c:List of 2
    .. .. ..$ f: chr "test"
    .. .. ..$ d:List of 1
    .. .. .. ..$ e:List of 2
    .. .. .. .. ..$ h: chr "one entry"
    .. .. .. .. ..$ g: chr "nice"
  </code></pre>
  
  <p>I know this is possible with recursion and the deepness.<br>
  But is there a way to do this with the help of <code>rapply</code> or something like that?</p>
  
  <p>Thanx in advance,<br>
