The purpose of this book is to provide examples to help in learning the software R.

The approach presented in this book is for the R beginner. After you gain experience, you can learn how to do tasks in other ways that may be more efficient.

You can search for terms and R functions using the search icon at the top of this page.

These examples show some R code to illustrate different aspects of R. The intent is for you to type the code in a R script to see the results. Typing is better than copying the code, as you might make a mistake in typing that allows you to learn how to debug your coding.
