Don't have your package "mess with" (e.g. assign) to the global
environment. Also, CRAN won't accept such packages.
A good rule of thumb is that if you find yourself using assign(), get(),
and <<-, or assigning explicitly to the global environment, it's a good
indicator that you're hiking up the w
Hi,
An other alternative using "assign" function
func <- function(){
X <- 5
assign("X", X, envir = .GlobalEnv)
}

Glad to see this query and the responses. You all just helped me to
eliminate the use of global variables from my R package. I knew they were
not recommended, but I didn't know how to get around using them.
Thanks!

OK thanks as:
myenv <- new.env(parent = emptyenv())
fun <- function(){
fun1 <- function(){
myenv$X <- 5
}
}
fun()
ls(myenv)
#X
X

By "At the top level" Hadley meant to put that code outside of the function
definition. In you source file that line should be very near the top,
before any function definitions. Then "myenv" will not be temporary (well

Thanks Dr Hadley,
but when I use a function the myenv remains temporary and I am to face the
same problem.
fun <- function(){
myenv <- new.env(parent = emptyenv())
fun1 <- function(){
myenv$X <- 5
}
}
ls(myEnv)

At the top level do:
myenv <- new.env(parent = emptyenv())
Then in your functions do
myenv$x <- 50
myenv$x
etc
You also should not be using data() in that way. Perhaps you want
R/sysdata.rda. See http://r-pkgs.had.co.nz/data.html for more details.

Dear All,
I am writing a GUIpackage that needs global variables.
I had many warning message when I checked the code as for example:
geteSet: no visible binding for global variable ‘curselectCases’
I would like to write a function that creates a global place for Objects to
be loaded as:
Fun <- fu
