我在 Ubuntu 12.04 上安装了 RStudio 0.97.168。当我尝试安装 gstat 库时,出现以下错误
install.packages("gstat", dependencies=TRUE)
Warning in install.packages :
cannot open: HTTP status was '407 Proxy Authentication Required'

Warning in install.packages :

我看到了仅适用于 Windows 操作系统的解决--intenet
方案setInternet(TRUE)
。
请提供有关我需要进行更改以支持我的大学代理的帮助?
