R and R-Studio Setup

In this article, you will learn to install R software and R Studio to get started with R programming.

The R software is a free software which you can install to write your programs and R-Studio is an IDE that helps to manage your workspace (you will learn about workspace later) and debugging, syntax highlighting, etc.

To learn R you don’t need R-Studio, however, we recommend installing it because it will make things little easier. Also, throughout this tutorial, we have used R-Studio for R programming examples.
