附录 A. 安装 R 和 RStudio
要开始使用 R，您需要获得自己的副本。本附录将向你介绍如何下载 R 和 RStudio，后者是一款让 R 更易于使用的软件应用程序。您将从下载 R 到打开第一个 R 会话。
R 和 RStudio 都是免费的，易于下载。
如何下载和安装 R
R 由一个国际开发团队维护，他们通过The Comprehensive R Archive Network 的网页提供 R 语言。网页顶部提供了三个下载 R 的链接：Windows、Mac 或 Linux。
Windows
要在 Windows 上安装 R，请单击 "下载 R for Windows "链接。然后点击 "基础 "链接。接下来，点击新页面顶部的第一个链接。该链接会下载一个安装程序，为 Windows 安装最新版本的 R。运行该程序，然后通过出现的安装向导进行操作。向导会将 R 安装到程序文件文件夹中，并在 "开始 "菜单中放置快捷方式。在计算机上安装新软件需要具备相应的管理权限。
Mac
要在 Mac 上安装 R，请点击 "下载 R for Mac "链接。然后，点击R-3.0.3 软件包链接（或最新版 R 的软件包链接）。系统会下载一个安装程序来指导你完成安装，安装过程非常简单。安装程序允许你自定义安装，但默认设置适合大多数用户。我从未发现有理由更改它们。如果你的电脑在安装新程序前需要密码，那么你需要在这里输入密码。
Linux
许多 Linux 系统都预装了 R，但如果你的系统已经过时，你还需要最新版本的 R。CRAN 网站在 "Download R for Linux "链接下提供了在 Debian、Redhat、SUSE 和 Ubuntu 系统上从源代码构建 R 的文件。点击该链接，然后按照目录路径找到你要安装的 Linux 版本。安装程序会根据你使用的 Linux 系统而有所不同。CRAN 通过将每组源文件与说明如何在系统上安装的文档或 README 文件进行分组来引导安装过程。
