什么是R？
R是包含了数据可视化功能的用于统计分析的编程语言。该语言通过Comprehensive R Archive Network（CRAN）拥有高度的可扩展性，该网络托管了10,000多个R包，用于生成出版数据，专用计算工具等。
虽然可以通过Debian或Ubuntu的源安装R，但本指南中的方法将确保您安装最新的稳定版本。
在Ubuntu 16.04和Debian 9 上安装R.
- 打开
/etc/apt/sources.list并将以下文本添加到文件末尾： Ubuntu： deb http://cran.rstudio.com/bin/linux/ubuntu xenial/ Debian： deb http://cran.rstudio.com/bin/linux/debian stretch-cran34/ - 添加CRAN网络的密钥ID： Ubuntu GPG密钥： sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9 Debian GPG密钥： sudo apt install dirmngr sudo apt-key adv --keyserver keys.gnupg.net --recv-key 'E19F5F87128899B192B1A2C2AD5F960A256A04AF'
- 更新源： sudo apt update
- 安装R二进制文件： sudo apt install r-base
从CRAN 下载软件包
- 打开R解释器： R
- 解释器将输出一些有关版本的信息。输入

RStudio IDE桌面
R解释器缺少调试器等功能，而大型项目可能需要这些功能。RStudio是一个IDE，它带有许多上手即用的开发工具。
- 下载RStudio： wget https://download1.rstudio.org/rstudio-xenial-1.1.414-amd64.deb
- 安装： sudo dpkg -i rstudio-xenial-1.1.414-amd64.deb 注意如果提示缺少依赖项，可以使用以下命令安装它们： sudo apt install -f
