R help - Mar 2012 - transfer local function objects to other environment - how?

Hello,

I have an empty environment named env. 
Now I want the locally created objects in some function (foo) to appear in env.
Within the function I want to have straight forward code, no assign operation or
env$x etc. in front of every command.
What is the best way to do that?

Example:      

foo <- function(){
  x <- 1
  y <- 2
}
env <- new.env() 

Now I want to evaluate foo() but have the local variables x and y appear in env.

Thanks 
---Mark

Try:

foo <- function(){
 x <- 1
 y <- 2
 environment()
}
e <- foo()

or you could just forget about the function and do:

e <- local({
  x <- 1
  y <- 2
  environment()
})

or

e <- as.environment(list(x = 1, y = 2))

or

library(proto)
p <- proto(x = 1, y = 2)
