title: Histogram of all values in a list in R
body: <p>I have a list <code>lst</code> with many objects in it. So <code>lst</code> would look something like</p>
  
  <pre><code>[[1]]
  2 4 11
  9 19 3
  
  [[2]]
   4 12 2
  17 2 13
  
  [[3]]
  6 8 2
  3 1 15
  
  [[4]]
  4 2 14
  17 8 20
  ...
  [[100]]
  16 8 23
  12 4 13
  </code></pre>
  
  <p>and so on. </p>
  
  <p>I want to create a single histogram and/or a density plot that contains every value in the list. If I try <code>hist(lst),</code> then I get the following error <code>Error in hist.default(lst) : 'x' must be numeric.</code> So I was wondering if there's a way to plot this in R? </p>
  
  <p>Thanks!</p>
