There are only two most important prerequisite to learn R programming. They are

  • R Programming Syntax and Basics
  • Learning Statistics

R Programming Syntax and Its Basics

Learning R syntax and language features are the first you have to take if you are new to this programming. If already have experience in programming such as C/C++, Java,etc, then learning the basics will not be hard for you.

Learning Statistics

R is a language for mathematics, especially statistics. You must be good in statistics to use R programming. It is good to watch some videos and learn statistics first before creating R programs.

If you are not good at statistics, then learn the basics of R and learn statistics later and come back to R for programming.

About R Tutorial

This tutorial is to help you learn the basics of R programming. We will include the statistical part eventually. Therefore, the tutorial is for beginners in R programming.
