title: Sets in R DataFrame
body: <p>I have a  csv that looks like</p>
  
  <pre><code> Deamon,Host,1:2:4,aaa.03
   Pixe,Paradigm,1:3:5,11.us
  </code></pre>
  
  <p>I need to read this into a dataframe for analysis but the 3rd column in my data is separated by : and need to be read like a set or list 1.e splitted by : so that it returns (1,2,4) . Is it possible to have a columns that has a class list in R . Or How best do you think i can approach this problem.</p>
