R is a powerful and free software system for data analysis and graphics, with over 1,200 add-on packages available. This book introduces R using SAS and SPSS terms with which you are already familiar. It demonstrates which of the add-on packages are most like SAS and SPSS and compares them to R's built-in functions. It steps through over 30 programs written in all three packages, comparing and contrasting the packages' differing approaches. The programs and practice datasets are available for download. The glossary defines over 50 R terms using SAS/SPSS jargon and again using R jargon. The table of contents and the index allow you to find equivalent R functions by looking up both SAS statements and SPSS commands. When finished, you will be able to import data, manage and transform it, create publication quality graphics, and perform basic statistical analyses. This new edition has updated programming, an expanded index, and even more statistical methods covered in over 25 new sections.

《R语言与统计分析》以数据的常用统计分析方法为基础，在简明扼要地阐述统计学基本概念、基本思想与基本方法的基础上，讲述与之相对应的R函数的实现，并通过具体的例子说明统计问题求解的过程。《R语言与统计分析》注重统计的思想性、方法的实用性和计算的可操作性。在内容的安排上不仅包含了基础统计分析中的探索性数据分析、参数估计与假设检验，还包括了非参数统计分析的常用方法、多元统计分析方法及贝叶斯统计分析方法。每一部分都通过具体例子重点讲述解决问题的思想、方法和在R中的实现过程。

Addressing the problem of inefficient collection and analysis of questionnaire data, this book proposes a methodology that uses R software. The author takes a practical approach to the subject, presenting principles first followed by detailed examples of their application to real data. He discusses principles of good questionnaire design, data management, capture, and manipulation and covers descriptive statistics, scoring, reliability, and missing data. The book focuses on R packages that are readily available and integrates discussion of their implementation and code throughout. All the data sets and R code packages are provided on a website.

Advanced R presents useful tools and techniques for attacking many types of R programming problems, helping you avoid mistakes and dead ends. With more than ten years of experience programming in R, the author illustrates the elegance, beauty, and flexibility at the heart of R. The book develops the necessary skills to produce quality code that can be used in a variety of circumstances. You will learn: -The fundamentals of R, including standard data types and functions -Functional programming as a useful framework for solving wide classes of problems -The positives and negatives of metaprogramming -How to write fast, memory-efficient code This book not only helps current R users become R programmers but also shows existing programmers what’s special about R. Intermediate R programmers can dive deeper into R and learn new strategies for solving diverse problems while programmers from other languages can learn the details of R and understand why R works the way it does.
