推荐答案

您可以在Windows上使用_winreg模块:首先在注册表中查找路径(例如，启动regedit.exe并使用其find函数).然后，您可以像我一样查询此路径以找到R的主目录:

You can use the _winreg module on windows: First find out the path in the registry (eg starting regedit.exe and using its find function). Then you can query this path as I did it once to find the home directory of R:

key = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, "Software\\R-core\\R")
value =  _winreg.QueryValueEx(key, "InstallPath")[0]

添加:

如果您不熟悉Windows注册表，请查看 http://en.wikipedia .org/wiki/Windows_Registry

If you are not familiar with the windows regstry: have a look at http://en.wikipedia.org/wiki/Windows_Registry
