[R] Equivalent of S> assign( , ,frame=1)

[Olivier Renaud]

Hi,
I'm new to R, and I certainly miss an obvious point. I looked in the doc
and the archieve, but could not find what is the R equivalent of the S
assign( , ,frame=1). I guess the question is like what is the equivalent
of the S frames and how to access them. As an example: 

oneprog <- function()
{
  initial()
  res <- subrout()
  return(res)
  }

initial <- function()
  {
  assign ("x", 2, frame=1)
  assign ("y", 3, frame=1)
  }

  
subrout <- function()
  return(x+y)

This works perfectly with S. I know that if I put subrout inside oneprog
and replace the call to initial by a simple x <- 2;y <-3, it will work
on R (and not on S). But initial is a routine I use in many different
programs, and therefore I don't want it inside a given one. Any help?
More general comments on this way of programming are also welcomed.
