本书注重实用性，是一本全面而细致的R指南，高度概括了该软件和它的强大功能，展示了使用的统计示例，且对于难以用传统方法处理的凌乱、不完整和非正态的数据给出了优雅的处理方法。作者不仅仅探讨统计分析，还阐述了大量探索和展示数据的图形功能。新版做了大量更新和修正，新增了近200页内容，介绍数据挖掘、预测性分析和高级编程。

Is the universe actually a giant quantum computer? According to Seth Lloyd, the answer is yes. All interactions between particles in the universe, Lloyd explains, convey not only energy but also information–in other words, particles not only collide, they compute. What is the entire universe computing, ultimately? “Its own dynamical evolution,” he says. “As the computation proceeds, reality unfolds.” Programming the Universe, a wonderfully accessible book, presents an original and compelling vision of reality, revealing our world in an entirely new light.

在线阅读本书 Widely considered one of the best practical guides to programming, Steve McConnells original CODE COMPLETE has been helping developers write better software for more than a decade. Now this classic book has been fully updated and revised with leading-edge practicesand hundreds of new code samplesillustrating the art and science of software construction. Capturing the body of knowledge available from research, academia, and everyday commercial practice, McConnell synthesizes the most effective techniques and must-know principles into clear, pragmatic guidance. No matter what your experience level, development environment, or project size, this book will inform and stimulate your thinkingand help you build the highest quality code. Discover the timeless techniques and strategies that help you: Design for minimum complexity and maximum creativity Reap the benefits of collaborative development Apply defensive programming techniques to reduce and flush out errors Exploit opportunities to refactoror evolvecode, and do it safely Use construction practices that are right-weight for your project Debug problems quickly and effectively Resolve critical construction issues early and correctly Build quality into the beginning, middle, and end of your project 点击链接进入中文版： 代码大全(第2版)
