This is the website for the 2nd edition of “R for Data Science”. This book will teach you how to do data science with R: You’ll learn how to get your data into R, get it into the most useful structure, transform it and visualize.
这是 《R 数据科学》 第二版的网站。本书将教你如何使用 R 进行数据科学：你将学习如何将数据导入 R、将其整理成最有用的结构，并对其进行转换与可视化。

In this book, you will find a practicum of skills for data science. Just as a chemist learns how to clean test tubes and stock a lab, you’ll learn how to clean data and draw plots—and many other things besides. These are the skills that allow data science to happen, and here you will find the best practices for doing each of these things with R. You’ll learn how to use the grammar of graphics, literate programming, and reproducible research to save time. You’ll also learn how to manage cognitive resources to facilitate discoveries when wrangling, visualizing, and exploring data.
在本书中，你将获得一套系统的数据科学实战技能。就像化学家学习如何清洗试管和整理实验室一样，你将学习如何清洗数据、绘制图形，以及更多相关技能。这些技能让数据科学成为可能，而你将在此处学到使用 R 完成这些任务的最佳实践。你将学会使用图形语法（grammar of graphics）、释义式编程（literate programming）以及可重复性研究（reproducible research）来节省时间。你还将学习如何管理认知资源，以便在数据清洗、可视化和探索过程中促进发现。
