## Overview
In R, the **`body()` function** is used to set or get the body of a function.

## Syntax
The syntax for _getting_ the body of a function using the `body()` function:
```
body(fun = sys.function(sys.parent()))
```
The syntax for _setting_ the body of a function:
```
body(fun, envir = environment(fun)) <- value
```
## Parameters
The `body()` function takes the following parameter values:
* **`fun`**: This represents the function object.
* **`envir`**: This represents the environment in which the function should be defined.
* **`value`**: This represents the value to make up the value of the function.

## Return value
This function returns the body of the specified function.


## Example of getting: 


# creating a function 
myfunction <- function(x) x^5

# getting the body of the function 
function_body <- body(myfunction ) 

# printing the body of the function
function_body

## Explanation 
* **Line 2**: We create a function and assign it to a variable `myfunction`.

* **Line 5**: We implement the `body()` function and the result is assigned to a variable `function_body`.

* Line 8: We print the variable `function_body`.

## Example of setting: 

# creating a function 
f <- function(x) x^5
function_body <- body(f) <- quote(5^x)
function_body

## Explanation 


* **Line 3**: We use the `body()` function to change the body of the function from `x^5` to `5^x`.

What is the body() function in R?

In R, the body() function is used to get or set a function's body, allowing modifications to the function's internal code.
