R help - Jul 2007 - passing a parameter to a file from command line

Hi,
 
I have a file fileFoo.R, say that contains these two lines, invoking
function foo that is specified in "foo_details.R":
 
source("foo_details.R")
foo(parameter1)
 
 
I want to specify and pass parameter1 in my command line when invoking R
in linux:   R --no-save <fileFoo.R.
 
How can I do that? 
And how can I retrieve the value of parameter1 in my fileFoo.R function
(something analogous to perl: my $parameter1=$ARGV[0])?
 
Thank you
 
Zava

Look at the commandArgs function to see if that does what you want.
