[R] What file did R read?

[BXC (Bendix Carstensen)]

When I run in BATCH mode I use a script (win2000):

c:\stat\r\%R_VERS%\bin\Rcmd BATCH -q --no-restore --no-save %1

Now I want to be able to print the filename of the program, i.e.
the value if the %1 argument, in the .Rout file. 

(Basically I want to write a piece of code in .First() which 
prints date and time and program run, so I need to get to the 
value of %1. Currently I let the operating system print the value 
of %1 to a file, and then read the contents of this file.
Clumsy, it works, but tricky to port to another machine.)

The commandArgs() does NOT capture the name of the input file.

Is it impossible to recover this filename from within R?
