title: Run Rscript interactive (readline()) in Command-line
body: <p>I use R scripts quite often. Until now I used them right in RStudio. Now I wish to pass a script to a friend and it should be as easy as possible. </p>
  
  <p>The command <code>Rscript</code> which you can simply use in cmd.exe is pretty nice and simple. But sometimes I need some additional information. I the Script I just can ask with <code>readline()</code> for an user input. But this only work if when I <code>source()</code> the file in R, but not in the command line with <code>Script</code> because this is not interactive. Is there an other command instead of Script or an option so you can run the script interactive from the command line?  </p>
