R Tutorial

R 是一种用于统计分析、图形表示和报告的编程语言和软件环境。R 由新西兰奥克兰大学的 Ross Ihaka 和 Robert Gentleman 编写，目前由 R Development Core Team 开发。R 在 GNU 通用公共许可证下免费提供，并为各种操作系统（如 Linux、Windows 和 Mac）提供了预编译的二进制版本。此编程语言被命名为 R ，其依据是两位 R 作者（Robert Gentleman 和 Ross Ihaka）名字的首字母，并且部分借鉴了贝尔实验室语言 S 的名字。

R is a programming language and software environment for statistical analysis, graphics representation and reporting. R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, and is currently developed by the R Development Core Team. R is freely available under the GNU General Public License, and pre-compiled binary versions are provided for various operating systems like Linux, Windows and Mac. This programming language was named R, based on the first letter of first name of the two R authors (Robert Gentleman and Ross Ihaka), and partly a play on the name of the Bell Labs Language S.
