R 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-onpackages, and R is a serious rival to all commercial statisticalpackages.

But R can be frustrating. Its 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. Each 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. Ifyou are an intermediate user, this book will be useful for expanding yourhorizons and jogging your memory (How do I do that KolmogorovSmirnovtest 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 its done in R.
