What is the environment() function in R?

Overview

In R, the environment() function returns the environment associated with a given function or formula.

An environment is a collection of objects such as functions, variables, and so on. Whenever we hit up the R interpreter, an environment is created. So at this point, any new variable we create is now contained in the new environment.

Syntax

environment(fun)

Parameter value

This function takes the parameter value, func, representing a formula function.

Example

# creating different R functions

function1 <- function() { 

  print("Hello World!")

}



function2 <- function() {

    print(2*3)

}



environment(function1)

environment(function2)

Explanation

  • Line 2–8: We create function1 and function2.
  • Line 10–11: We implement the environment() method on the functions we created.
