Great play, that introduced the word "robot" into English, looks to a future in which all workers are automatons. They revolt when they acquire souls (i.e., when they gain the ability to hate) and the resulting catastrophe make for a powerful and deeply moving theatrical experience. Paul Selver translation.

R.U.R.--written in 1920, premiered in Prague in 1921, and first performed in New York in 1922--garnered worldwide acclaim for its author and popularized the word robot. Mass-produced as efficient laborers to serve man, Capek's Robots are an android product--they remember everything but think of nothing new.

本书分为上下两部分，旨在指导你如何使用R，并提供练习的机会。上半部分主要介绍R的技术细节和使用技巧。每章都简要介绍了一组不同的数据类型（例如第4章介绍向量、矩阵和数组）或概念（例如第8章介绍分支和循环）。下半部分更侧重实践，展示了从输入数据到发布结果这一标准的数据分析流程。 即使你没有任何编程基础，也能顺利阅读本书。 编写简单的R程序，知道R语言能做什么 使用向量、数组、列表、数据框和字符串等数据类型 掌握条件语句以及分支和循环控制语句 应用R的扩展包，将你自己的工作成果打包发给其他人 清理从各种来源导入的数据 通过可视化和汇总统计理解数据 使用统计模型传递关于数据的定量判断并进行预测 了解编写数据分析代码时出现错误的应对措施
