A Survivor's Guide to R
An Introduction for the Uninitiated and the Unnerved

Additional resources:


June 2014 | 488 pages | SAGE Publications, Inc
Focusing on developing practical R skills rather than teaching pure statistics, Dr. Kurt Taylor Gaubatz’s A Survivor’s Guide to R provides a gentle yet thorough introduction to R. The book is structured around critical R tasks, and focuses on applied knowledge, rather than abstract concepts. Gaubatz’s easy-to-read approach helps students with little or no background in statistics or programming to develop real-world R skills through straightforward coverage of R objects and functions. Focusing on real-world data, the challenges of dataset construction, and the use of R’s powerful graphing tools, the guide is written in an accessible, sympathetic, even humorous style that ensures students acquire functional R skills they can use in their own projects and carry into their work beyond the classroom.

“The guide is detailed enough that students could practice these operations outside the classroom until they mastered them, which means that more class time can be spent discussing the conceptual issues in statistics.”

Ole J. Forsberg, Oklahoma State University

“R's visualization tools and its powerful graphics capabilities . . . make this book a popular choice for many applications.”

Charlotte Tate, San Francisco State University

“A strength is the author's thorough approach to the code without being . . . dull.  I very much appreciate that the author describes R code idiosyncrasies while keeping the text light.”

Yulan Liang, University of Maryland, Baltimore

“[This book] does an excellent job of guiding readers through pitfalls common to R's data handling idiosyncrasies—pitfalls usually learned after hours of frustration and lamentation. The conversational, and at times humorous, style makes for a readable, enjoyable, and relaxed examination of a powerful computation tool with a steep learning curve. Each chapter is compartmentalized enough to be read separately, but the author includes chapter references . . . to tie the guide together as a whole . . . The author covers the full spectrum, plus, thankfully, quite a bit of  material not usually included in other R introductions . . . The author covers the material in depth with nicely done examples.  I was also very happy to see that the author included a section on programming etiquette in R—very nice.”

A. Dean Monroe, Angelo State University

“I very much appreciate the development of a text primarily devoted to the students and practitioners who are first-time users of R . . . It is a very gentle and easy-to-read introduction to R for anyone who might have been afraid of learning programming language . . . It [is] very easy to read and follow . . . The flow of the topics is logical and natural for teaching any computational language. With a good sense of humor, the text is highly user-friendly.”

Professor David Han, University of Texas, San Antonio

My university and department has yet to allow me to teach R instead of SPSS. However, this is a terrific text, and I hope to see an updated version soon when it becomes clear that we should be teaching and using R instead of, or in conjunction with, SPSS.

Very useful for supporting learning of R. Good introduction and useful for reference.

Dr Mark Ramsden

This is a helpful book for students doing data analysis with R.

A "Survivor's guide to R" is a nice introduction for the more technical details of R which are essential to make fully use of R's statistical capacities. It is useful for beginners of R who have little or no experience with programming languages. It is easy and nice to read (at least as such a technical topic can be).

SAGE Research Methods is a research methods tool created to help researchers, faculty and students with their research projects. SAGE Research Methods links over 175,000 pages of SAGE’s renowned book, journal and reference content with truly advanced search and discovery tools. Researchers can explore methods concepts to help them design research projects, understand particular methods or identify a new method, conduct their research, and write up their findings. Since SAGE Research Methods focuses on methodology rather than disciplines, it can be used across the social sciences, health sciences, and more.

With SAGE Research Methods, researchers can explore their chosen method across the depth and breadth of content, expanding or refining their search as needed; read online, print, or email full-text content; utilize suggested related methods and links to related authors from SAGE Research Methods' robust library and unique features; and even share their own collections of content through Methods Lists. SAGE Research Methods contains content from over 720 books, dictionaries, encyclopedias, and handbooks, the entire “Little Green Book,” and "Little Blue Book” series, two Major Works collating a selection of journal articles, and specially commissioned videos.
