我知道有很多关于在Linux Mint上升级R的文章，但是这些文章对我来说都没有用。我遵循了这个github页面上的指示： “ https://github.com/duckmayr/install-update-r-on-linux”
当我更新（sudo apt update）时，所有功能都运行顺利，并且在输出的一行中看到了这一点：
Hit:12 http://archive.linux.duke.edu/cran/bin/linux/ubuntu bionic-cran35/ InRelease
但是当我加载R时，它仍然保持版本3.4.4
我尝试删除R并用sudo apt install r-base重新安装，但遇到此消息：
Reading package lists... Done
Building dependency tree
Reading state information... Done

我正在运行linux mint 19肉桂版本3.8.9
任何帮助将不胜感激。
谢谢！
