At the top level do:
myenv <- new.env(parent = emptyenv())
Then in your functions do
myenv$x <- 50
myenv$x

You also should not be using data() in that way. Perhaps you want

Beware of the is.* functions:
* is.object() does not test the usual definition of objects
* is.vector() does not test the usual definition of vectors
* is.numeric() does not work the same way as is.character() or is.integer()
* is.Date() doesn't exist
* is.nan() doesn't return TRUE for some NaNs
You really want to use the names of the list since lists can contain
null. I'd recommend something more like:
getElement <- function(x, i, default) {
if (i %in% names(x)) return(x[[i]])
default

document to learn about S4.
The most important thing to get about OO in R is that methods belong
to generic functions, not like classes, as in most other program

There are a couple of approaches here:

Because it doesn't work very well, as you've discovered.
There's an equivalent join_all in plyr.

No, and it's not currently on the to do list

Are the functions exported or internal?
# Use for internal functions
pkg <- asNamespace("mypackage")
# Use for exported functions:
pkg <- "package:mypackage"

You
After uploading your package via ftp, in your email to
c...@r-project.org you need to state that you agree to the CRAN
repository policy
(http://cran.r-project.org/web/packages/policies.html)

If you have a million levels is it really necessary to use a factor? I'm
not sure what advantages it will to have to a string in this circumstance
(especially since you don't seem to know the levels a priori but have to
learn them from the data).
