[R] How to provide argument when opening RGui from an external application

[Sébastien]

Dear R-users,

I have written a small application (in visual basic) that automatically 
generate some R scripts. I would like to execute these scripts when my 
application is being closed.
My problem is that I don't know how to pass the 
'source(c:/.../myscript.r)' instruction when I programmatically start 
RGui. Tinn-R is capable of doing such things, so I guess there must be a 
way to pass arguments to RGui.

Any advice or link to relevant references would be greatly appreciated.
