title: How to select items from each vector of the list in R
body: <p>I would like to select the third item from each vector of the list below.
  I tried in this way, but I got problems at level 2. I found the function select.list() but I do not know how to apply it. 
  Any suggestions? Many thanks.</p>
  
  <pre><code>newlist =  x[[1:140]][3]
  List of 140
  chr(0)
  chr [1:7] Brachy leaf N11428394 1 
  chr [1:7] Brachy leaf N10508942 141 
  chr(0) 
  chr [1:7] Brachy leaf N35663 5 
  chr [1:7] Brachy leaf N12458414 1
