How to install a specific version of a package in R

在使用R语言完成数据分析的过程中，很多时候，因为项目实际需要，我们应该指定某些库文件的安装包的版本，这个时候，我们可以基于devtools包中的函数install_version来完成。

这里，我们以安装库文件ggplot2的安装包的版本号为3.3.6为例来说明，即

devtools::install_version("ggplot2",version = "3.3.6",repos = "https://mirrors.tuna.tsinghua.edu.cn/CRAN/")
1

说明如下：

• version

版本号

• repos

仓库地址，这里将其指定为清华大学开源镜像站的地址

devtools::install_version("ggplot2",version = "3.3.6",repos = "https://mirrors.tuna.tsinghua.edu.cn/CRAN/")
