How can I read command line parameters from an R script?

Question

I want to supply some command-line parameters from a R script I have. And it runs on windows.

I just want it read the command line parameters from a R script, Can someone help me with it?

Answer 1

I want to say some points on that:

1. Command-line parameters are obtainable via commandArgs(), so for understanding that in detail, write help(commandArgs).
2. You can use Rscript.exe on all operating systems, including Windows. It will support commandArgs(). 
3. There are two add-on packages on CRAN -- getopt and optparse -- which were both written for command-line parsing.
