GitHub
是一个在线平台，方便你共享你的工作与协作编程。也有一些类似平
台例如
GitLab
。本节重点介绍
GitHub
，因为到目前为止它在
R
程序员中最流
行。另外通过 devtools::install_github() 命令可实时预览并更新可供安
装的包的版本。这使得
GitHub
包轻松获得最新功能。并且
GibHub
使你的工
作分享起来更容易，从而与别人高效合作，没有
CRAN
包的那些限制条件。
比如说，为了安装
GitHub
版的
benchmarkme
包，你应输入如下命令：
devtools::install_github("csgillespie/benchmarkme")
需要注意的是，
csgillespie
是
GitHub
用户名，benchmarkme 是包名。将上
面的代码中 csgillespie 替换成 robinlovelace，将安装
Robin
版的包。
这对于多人快速协作很有用的，但你必须记住
GitHub
包不能使用 update.
packages （见第
2
章的“更新
R
包”一节）命令自动更新。
