About this book

A Survivor's Guide to R provides a gentle, but thorough, introduction to R. It is an ideal supplement to any introductory statistics text or a practical field guide for those who want to use the powerful R language for statistical analysis in their own research. A Survivor's Guide to R focuses on providing students with the real-world R skills that are often hard to get to in statistics classes: basic data management and manipulation, and working with R graphics. A Survivor's Guide to R is designed to get students with little or no background in statistics or programming started on R within the context of a statistics class, and to ensure that they have acquired functional R skills that they can continue to use as they move on to their own projects.

A Survivor's Guide to R begins with a straightforward approach to understanding R objects, and then moves systematically through the use of R to transform, sort, and aggregate data; to work with complex textual and date/time data; and to effectively build on R's default graphics capabilities to produce highly customized and effective graphics. It focuses on working with real-world data, with – on reading data in different formats and the challenges of missing data. A Survivor's Guide to R is intended for those with little to no statistics or programming experience – students and other new users who are likely to find their first encounter with R more than a little intimidating. It is written in an accessible and sympathetic style that makes minimal assumptions about user skills, and provides frequent warnings about common pitfalls that must be avoided along the road to R mastery. .

"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
