In R programming, what is the function used to perform specific tasks called?

1. Procedure

2. Method

3. Function

4. Subroutine

The correct answer is: Function

In R programming, the term that is used to describe a block of code designed to perform specific tasks is "function." A function in R is a self-contained piece of code that takes inputs (arguments), processes them, and returns an output. This allows for modular programming, making it easy to reuse code and maintain it. Functions can simplify complex problems by breaking them down into manageable parts, promoting clarity and reducing redundancy. When we define a function in R, we specify its name and include any parameters it will take. The body of the function contains the operations or computations that the function performs, culminating in a return statement to provide the desired result. This fundamental concept is critical not only in R but in many programming languages, as it aids in organizing code logically. While terms like "procedure," "method," and "subroutine" do exist in the context of programming, they can carry slightly different meanings depending on the language or context they are used in. "Procedure," for instance, typically refers to a function that does not return a value, while "method" often indicates a function that is associated with an object in object-oriented programming. "Subroutine" generally refers to a sequence of instructions that can be called from different parts of a program
