Open Source R Books
The R language (and open-source software) is the de facto standard among statisticians for the development of statistical software, and is widely used for statistical software development and data analysis. R is a modern implementation of S, one of several statistical programming languages designed at Bell Laboratories.
R is much more than a programming language. It’s an interactive environment for performing statistics. R offers a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible. The ability to download and install R packages is a key factor which makes R an excellent language to learn. Packages are the fundamental units of reproducible R code. They include reusable R functions, the documentation that describes how to use them, and sample data. The CRAN package repository hosts over 10,000 packages, and Bioconductor hosts nearly 1,300 packages.
R is available as Free Software under the terms of the Free Software Foundation’s GNU General Public License in source code form.
We have published a series covering the best open source programming books for other popular languages. Read them here.

This tutorial manual provides a comprehensive introduction to R, a software package for statistical computing and graphics.
R supports a wide range of statistical techniques and is easily extensible via user-defined functions. One of R’s strengths is the ease with which publication-quality plots can be produced in a wide variety of formats.
The manual is released under an open source license.
An Introduction to R is one of the R Manuals. Visit the Comprehensive R Archive Network to read the others.

The R Inferno is an essential guide to the trouble spots and oddities of R. The book shares a lot of useful information and maintains the reader’s interest. The book provides many useful techniques and tips for reducing memory usage, improving performance, and avoiding errors in computational analysis.
R is regarded as an excellent computing environment for most data analysis tasks. R is free, released under an open-source license, and has thousands of contributed packages. It is used in such diverse fields as ecology, finance, genomics and music.
Chapters are headed:
The book is illuminated with famous Botticelli artwork: The Giants, The Sowers of Discord, and The Thieves.
Note: The book is not officially released under an open source license, but Patrick Burns seems fine about it being treated as open.

ModernDive is a textbook that teaches students how to:
The book uses many R packages, and makes effective use real-world data sets to communicate key concepts. The book offers good treatment of the basics of data analysis (data wrangling and data exploration and data visualization, including the elegant roadmap for selecting a chart type shown below) and statistical concepts including simulation, regression and hypothesis testing.
The book also aims to give students an understanding of the overarching data analysis process, including concepts like reproducibility and telling stories with data.

Little Book of R for Biomedical Statistics is a simple introduction to biomedical statistics using the R statistics software.
This booklet tells you how to use the R software to carry out some simple analyses that are common in biomedical statistics. In particular, the focus is on cohort and case-control studies that aim to test whether particular factors are associated with disease, randomised trials, and meta-analysis.
This booklet assumes the reader has some basic knowledge of biomedical statistics, and the principal focus of the booklet is not to explain biomedical statistics analyses, but instead to explain how to carry out these analyses using R.
The booklet examines:

Here are good free-to-download programming books.
- Learning Statistics with R – covers the contents of an introductory statistics class, as typically taught to undergraduate psychology students, focusing on the use of the R statistical software.
The license terms of these books are unclear.
- Population Health Data Science with R – introduces R to public health epidemiologists and health care analysts conducting population health analyses.
- Spatial Epidemiology Notes: Applications and Vignettes in R – presents a relatively brief, non-jargony overview of how practicing epidemiologists can apply some of the extremely powerful spatial analytic tools that are easily available to them.
