 Then what you really want to do is write a _function_ that takes
arguments, and not a script. Tell your users something like:

 Do 'source("foo.R")' and then call the fnord function with your data
set: fnord(x).

Your foo.R file looks like this:

 fnord =function(x){
   print(x) # etc
 }

It's even possible to save functions to .RData files and then tell
your users to attach() them, thus not putting objects in their working
spaces.

And the next step is to write a package for your function...
