R help - Sep 2005 - what's the best way to save global variables?

I am writing a kind of long program in R and I have some variables which I want
to be globals. Where should I save them?  I was thinking to create a function
wich initialize all the global variables and then whenever I need them, I call
this function.
What if I create a file glob.R with 
var1<-val1
var2<-val2
.....
etc. 
 
How do I include this file in my other files/function . Is there in R some kind
of   include("glob.R") or something?
thank you,
Johan

In most cases, you would write a function that would
return an object of class list, the components of
which would be the values you want to use later.
For example

myfun <- function([stuff]){

  [stuff]

  return(list = (var1 = val1, var2 = val2)
}

and your call would be

glob <- myfun([stuff])

and you would access val1 with

glob$var1

Use

source("glob.R")
