This is the only introduction you'll need to start programming in R, the open-source language that is free to download, and lets you adapt the source code for your own requirements. Co-written by one of the R Core Development Team, and by an established R author, this book comes with real R code that complies with the standards of the language. Unlike other introductory books on the ground-breaking R system, this book emphasizes programming, including the principles that apply to most computing languages, and techniques used to develop more complex projects. Learning the language is made easier by the frequent exercises and end-of-chapter reviews that help you progress confidently through the book. Solutions, datasets and any errata will be available from the book's web site. The many examples, all from real applications, make it particularly useful for anyone working in practical data analysis.

《计算机程序设计艺术(第1卷):基本算法(英文版·第3版)》主要内容：关于算法分析的这多卷论著已经长期被公认为经典计算机科学的定义性描述。迄今已出版的完整的三卷已经组成了程序设计理论和实践的惟一的珍贵资源，无数读者都赞扬Knuth的著作对个人的深远影响，科学家们为他的分析的美丽和优雅所惊叹，而从事实践的程序员已经成功地将他的“菜谱式”的解应用到日常问题上，所有人都由于Knuth在书中表现出的博学、清晰、精确和高度幽默而对他无比敬仰。第1卷为基本算法，分“基本概念”和“信息结构”两章。本卷以基本的编程概念和技术开始，然后讲述信息结构——计算机内信息的表示法、数据元素间的结构关系以及处理它们的有效方法。

本书是一本不可多得的字符串匹配方面的专业书籍。书中对串匹配问题进行了系统化的分类，从实际效果出发，着重详细介绍了串匹配领域内效果最好的若干种算法。并且给出了具有统一接口的算法伪码，使读者能清晰理解算法原理，易于实现算法编程，从而提高专业水平。此外，书中通过严谨的理论分析和大量实验数据，说明了每种算法在实际应用中的适用范围，由此提供了良好的应用指导，解决了串匹配算法的最佳适用性问题。 本书可帮助本领域的研究人员从整体上把握字符串匹配方面的脉络，而其他相关领域的人员也可借助本书非常清晰地了解串匹配问题的概况。

本书是Sedgewick彻底修订和重写的C算法系列的第一本。全书分为四部分，共16章，第一部分“基础知识”（第1-2章）介绍基本算法分析原理。第二部分“数据结构”（第3-5章）讲解算法分析中必须掌握的数据结构知识，主要包括基本数据结构，抽象数据结构，递归和树。

本书是Sedgewick彻底修订和重写的丛书中的第二本，集中讲解图算法。全书共有6章（第17-22章）。第17章详细讨论图性质和类型，第18-22章分别讲解图搜索、有向图和DAG、最小生成树、最短路径以及网络流。 　　书中提供了用C语言描述的完整算法源程序，并且配有丰富插图和练习。作者用简洁的实现将理论和实践成功地结合了起来，这些实现均可在真实应用上测试，使得本书自问世以来备受程序员的欢迎。 本书可作为高等院校计算机相关专业算法与数据结构课程的教材和补充读物，也可供自学之用。

"This is an eminently readable book which an ordinary programmer, unskilled in mathematical analysis and wary of theoretical algorithms, ought to be able to pick up and get a lot out of.." - Steve Summit, author of C Programming FAQs Sedgewick has a real gift for explaining concepts in a way that makes them easy to understand. The use of real programs in page-size (or less) chunks that can be easily understood is a real plus. The figures, programs, and tables are a significant contribution to the learning experience of the reader; they make this book distinctive. - William A. Ward, University of South Alabama Robert Sedgewick has thoroughly rewritten and substantially expanded his popular work to provide current and comprehensive coverage of important algorithms and data structures. Many new algorithms are presented, and the explanations of each algorithm are much more detailed than in previous editions. A new text design and detailed, innovative figures, with accompanying commentary, greatly enhance the presentation. The third edition retains the successful blend of theory and practice that has made Sedgewick's work an invaluable resource for more than 250,000 programmers! This particular book, Parts 1-4, represents the essential first half of Sedgewick's complete work. It provides extensive coverage of fundamental data structures and algorithms for sorting, searching, and related applications. The algorithms and data structures are expressed in concise implementations in C, so that you can both appreciate their fundamental properties and test them on real applications. Of course, the substance of the book applies to programming in any language. Highlights * Expanded coverage of arrays, linked lists, strings, trees, and other basic data structures * Greater emphasis on abstract data types (ADTs) than in previous editions * Over 100 algorithms for sorting, selection, priority queue ADT implementations, and symbol table ADT (searching) implementations * New implementations of binomial queues, multiway radix sorting, Batcher's sorting networks, randomized BSTs, splay trees, skip lists, multiway tries, and much more * Increased quantitative information about the algorithms, including extensive empirical studies and basic analytic studies, giving you a basis for comparing them * Over 1000 new exercises to help you learn the properties of algorithms Whether you are a student learning the algorithms for the first time or a professional interested in having up-to-date reference material, you will find a wealth of useful information in this book.
