How can I assign the result of an operation from within a function to the global environment?

+2
−0

I have a function that which does some calculations. I would like to assign the result of the function to the global environment from within the function, how do I proceed?

A minimal example:

meanFUN <- function(x) {
 mean(x, na.rm = TRUE)
}

How can I assign the result from mean(x, na.rm = TRUE) from within the function to the global environment?

Note that super-assigning directly to the global environment is generally frowned upon as each time the function is called it will change (or create) that global variable. It is preferable for the function to return the value and then it can be assigned - this way you don't have to worry about the global value changing in unpredictable ways.
