Statistics in a Nutshell is a clear and concise introduction and reference for anyone new to the subject. Thoroughly revised and expanded, this edition helps you gain a solid understanding of statistics without the numbing complexity of many college texts.Each chapter presents easy-to-follow descriptions, along with graphics, formulas, solved examples, and hands-on exercises.
Welcome to the R Cookbook 2nd EditionR is a powerful tool for statistics, graphics, and statisticalprogramming. It is used by tens of thousands of people daily to performserious statistical analyses. It is a free, open source system whoseimplementation is the collective accomplishment of many intelligent,hard-working people. There are more than 10,000 available add-on packages, and Ris a serious rival to all commercial statistical packages.But R can be frustrating. It’s not obvious how to accomplish many tasks,even simple ones. The simple tasks are easy once you know how, yetfiguring out that “how” can be maddening.This book is full of how-to recipes, each of which solves a specificproblem. The recipe includes a quick introduction to the solutionfollowed by a discussion that aims to unpack the solution and give yousome insight into how it works.
We know these recipes are useful and weknow they work, because we use them ourselves.The range of recipes is broad. It starts with basic tasks before movingon to input and output, general statistics, graphics, and linearregression. Any significant work with R will involve most or all ofthese areas.If you are a beginner, then this book will get you started faster. If youare an intermediate user, this book is useful for expanding yourhorizons and jogging your memory (“How do I do that Kolmogorov–Smirnovtest again?”).The book is not a tutorial on R, although you will learn something bystudying the recipes. It is not a reference manual, but it does containa lot of useful information. It is not a book on programming in R,although many recipes are useful inside R scripts.Finally, this book is not an introduction to statistics.
Many recipesassume that you are familiar with the underlying statistical procedure,if any, and just want to know how it’s done in R. The RecipesMost recipes use one or two R functions to solve a specific problem.It’s important to remember that we do not describe the functions indetail; rather, we describe just enough to solve the immediate problem.Nearly every such function has additional capabilities beyond thosedescribed here, and some have amazing capabilities.
We strongly urge youto read the function’s help page. You will likely learn somethingvaluable.Each recipe presents one way to solve a particular problem. Of course,there are likely several reasonable solutions to each problem. When weknew of multiple solutions, we generally selected the simplest one. Forany given task, you can probably discover several alternative solutionsyourself. This is a cookbook, not a bible.In particular, R has literally thousands of downloadable add-onpackages, many of which implement alternative algorithms and statisticalmethods. This book concentrates on the core functionality availablethrough the basic distribution combined with several important packages knowncollectively as the tidyverse.The, itsoriginator and one of its core maintainers:The tidyverse is a set of packages that work in harmony because they sharecommon data representations and API design.
The tidyverse package is designedto make it easy to install and load core packages from the tidyverse in asingle command. The best place to learn about all the packages in thetidyverse and how they fit together is.
A Note on TerminologyThe goal of every recipe is to solve a problem and solve it quickly.Rather than laboring in tedious prose, we occasionally streamline thedescription with terminology that is correct but not precise. A goodexample is the term generic function. We refer to print(x) andplot(x) as generic functions because they work for many kinds of x,handling each kind appropriately. A computer scientist would wince at ourterminology because, strictly speaking, these are not simply“functions”; they are polymorphic methods with dynamic dispatching.
Butif we carefully unpacked every such technical detail, the essentialsolution would be buried in the technicalities. So we just call themfunctions, which we think is more readable.Another example, taken from statistics, is the complexity surroundingthe semantics of statistical hypothesis testing. Using the strictlanguage of probability theory would obscure the practical applicationof some tests, so we use more colloquial language when describing eachstatistical test. See the introduction to Chapter for more about how hypothesis tests arepresented in the recipes.Our goal is to make the power of R available to a wide audience bywriting readably, not formally. We hope that experts in their respectivefields will understand if our terminology is occasionally informal. Software and Platform NotesThe base distribution of R has frequent and planned releases, but thelanguage definition and core implementation are stable. The recipes inthis book should work with any recent release of the base distribution.Some recipes have platform-specific considerations, and we have carefullynoted them.
Those recipes mostly deal with software issues, such asinstallation and configuration. As far as we know, all other recipes willwork on all three major platforms for R: Windows, macOS, and Linux/Unix. Other Resources On the webThe mothership for all things R is the. From there you can downloadR for your platform, add-on packages, documentation, and source code as well asmany other resources.Beyond the R project site, we recommend using an R-specific searchengine, such as, created by Sasha Goodman.You can use a generic search engine, such as Google, but the “R”search term brings up too much extraneous stuff. See Recipe,“Searching the Web for Help” for more about searching the web.Reading blogs is a great way to learn about R and stay abreast ofleading-edge developments. There are surprisingly many such blogs,so we recommend following two blog-of-blogs:, created by Tal Galili,.

The world ofstatistics is benefiting tremendously from their work. The R Studio Community Discussion participants were very helpful in workshopping ideas around how to explain many things. And the staff and leadership of R Studio were supportive in so many little and big ways.
We owe them a debt of gratitude for all they have given back to the R community.We wish to thank the book’s technical reviewers: David Curran, Justin Shea, andMAJ Dusty Turner. Their feedback was criticalfor improving the quality, accuracy, and usefulness of this book.
Our editors, Melissa Potter and Rachel Monaghan, were helpful beyond imagination and theyfrequently prevented us from publicly demonstrating our ignorance. Our production editor, Kristen Brown, is the envy of all technical authors because of her speed and her proficiency with both markdown and git.Paul would like to thank his family for their support and patience during the creation of this book.JD would like to thank his wife Mary Beth and daughter Ada for their patience with all the early mornings and weekends that JD spent with his face in the laptop working on this book.
