title: run R script from .bat (batch file)
body: <p>I am trying to run a r script using batch file. Currently I am using 
  <code>start"" "shortcut of R"</code> to open R. However, I wanna R automatically run a r script that I have saved on the computer. </p>
  
  <p>Possibly R will be closed after running the script and user do not see R running. </p>
  
  <p>Is that possible? Thanks a lot!</p>
