使用代理连接的 Rstudio 包下载问题

Question

这是我在互联网上寻找解决问题的 2 天，但没有成功。 我在工作中下载了 Rstudio，并尝试安装一些软件包。

当我把例如放在 R 中时：

> install.packages("readxl")

返回

我上网查了一下，问题好像是我公司代理的连接问题（每次上网都要输入用户名和密码）

我尝试在 C:\Users\your user name\Documents 中的 .Renviron 文件中添加我在互联网上找到的以下代码：

options(internet.info = 0)   
http_proxy = https:// user_id:password@your_proxy:your_port    
http_proxy_user = user_id:password

我替换了 user_id 和密码
我在以下位置找到了我的代理：start>run>cmd>ipconfig 它的格式为 xxxxx.xxx.ca（一些字母替换了“x”）
对于我的端口，我放了 8080

我也尝试过直接下载压缩包的zip文件，但也不行。

我很想找到解决办法

您是否尝试将.Renviron 放在C:\Users\your user name\ 中？
