有些包没找到？

Question

当我打开我的R.它显示了一些警告信息，这意味着我丢失了一些包，就像

一样

Warning message:
package "methods" in options("defaultPackages") was not found 
During startup - Warning messages:
1: package ‘datasets’ in options("defaultPackages") was not found 
2: package ‘utils’ in options("defaultPackages") was not found 
3: package ‘grDevices’ in options("defaultPackages") was not found 
4: package ‘graphics’ in options("defaultPackages") was not found 
5: package ‘stats’ in options("defaultPackages") was not found 
6: package ‘methods’ in options("defaultPackages") was not found

然后我无法使用一些基本功能，而且我重新安装了R两次，它仍然没有用。任何人都知道如何处理这种情况？

根据R帮助中的link，您的R路径可能已损坏：

您可以调整PATH变量或尝试在另一个文件夹中重新安装R并从那里开始。这应该可以解决问题。
