A function in R is defined as a set of statements grouped together to perform a specific task. User-defined functions can be created in R using the "function" keyword and follow a syntax that includes the function name, arguments, function body, and optional return value. Functions allow users to reuse code for common tasks.

2. FUNCTION DEFINITION
A function is a set of statements organized
together to perform a specific task.
An R function is created by using the keyword
function.

3. USER DEFINED FUNCTION
• We can create user-defined functions in R.
• They are specific to what a user wants and once
created they can be used like the built-in functions.

4. Syntax
Function_name <- function(arguments){
function_body
return (return)
}
Where function_name is the name of the function,
arguments are the input arguments needed by the
function,
function_body is the body of the function,
return is the return value of the function.
