[R] environments

Hi there,

I try to understand the usage of environments but I'm not sure if I get it. I 
wrote a test script like this:

testenv <- new.env(environment())

myfun <- function(x) {
	testenv$testvar_2 <- 20
environment(myfun) <- testenv

testenv$testvar <- 10
ls(envir = testenv)

Now, I was wondering if there is any way to create new variables in my 
environment without this "testenv$...". I know that I can access it that way if 
I do an attach(testenv) before, but that does not help when creating new ones...
Do I completely misunderstand the concept?
I'm just looking for an elegant way to access objects of a graphical 
userinterface from each handler-function and so on. And I thought it might be 
good to pack them into an environment...
