Dear Debrata,

if this is what you mean by "submitting a job", so just login in 
remotely and starting the job manually,
you can do what Noah suggested in a more convenient way:

- many Scp / Ftp applications allow "editing on the server", meaning you 
don't have to transfer the file after every change manually. I use a 
combination of winscp and Notepad++ normally for this.

- read the man pages of the unix command screen (by typing "man screen" 
on the server) to see how to get a permanent session that stays there 
for you, after you detach from it.

Be sure to test your scripts on your local system before with easy (and 
faster examples). For packages: The same requirements apply to the R on 
server as for your local system, you simply need the same packages there.
