title: R Convert a String<List> to List
body: <p>I am importing a column from a file. The column is formed using a collect_list function. So every entry looks like follows:</p>
  
  <pre><code>[1,5,10]
  [27,30,1,33,40]
  [1,2,8,20,30,50,...]
  </code></pre>
  
  <p>I am trying to read this column into R and convert every row into a list. When I read I get a string for every row of the form:</p>
  
  <pre><code>"[1,5,10]"
  </code></pre>
  
  <p>What should I do to read this column into a list? Thanks!</p>
