【问题描述】：

我最近安装了forecast 包，使用install.packages()。
最新版本（6.1）已成功安装，但我想安装预测包版本5.9。所以我用了：

install.packages('http://cran.rstudio.com/src/contrib/Archive/forecast/forecast_5.9.tar.gz', repos=NULL, type='source')

但是在使用库时出现错误：

install.packages('http://cran.rstudio.com/src/contrib/Archive/forecast/forecast_5.9.tar.gz', repos=NULL, type='source')
Installing package into ‘C:/Users/.../Documents/R/win-library/3.2’

【问题讨论】：

如果在安装 5.9之前首先删除 forecast6.1 会发生什么？

标签： r installation package

【解决方案1】：

这里是安装预测版本 5.9 的方法（如果你已经安装了预测 6.1，这不是问题，它会单独安装 5.9，这意味着你会在安装的包中看到两个预测包）。转到链接https://cran.r-project.org/src/contrib/Archive/forecast/ 下载预测5.9（只需点击它，它将开始下载文件。现在打开 R 工作室，单击安装包并将安装从更改为：包存档文件（只需浏览到 zip 文件的位置）。您的包将被安装。在我的情况下使用预测包时，当两个预测包都加载时它不起作用（使用预测包的功能）。所以我使用预测 5.9 确保没有加载 6.1。希望有帮助
