title: Running an R script from command line (to execute from python)
body: <p>I'm currently trying to run an R script from the command line (my end goal is to execute it as the last line of a python script).  I'm not sure what a batch file is, or how to make my R script 'executable'. Currently it is saved as a .R file.  It works when I run it from R.<br>
  How do I execute this from the windows command prompt line? Do i need to download something called Rscript.exe? Do I just save my R script as an .exe file? Please advise on the easiest way to achieve this.<br>
  R: version 3.3   python: version 3.x  os: windows </p>
