我已经安装了两个版本的 R（Base-R 和 Microsoft R）。实际上 Microsoft R 版本是默认的，现在我想更改为 Base-R。在 RStudio -> Options 中更改版本非常简单。但是当我选择 Base-R 版本时，我收到以下消息：
“您需要退出并重新打开 RStudio 才能使此更改生效”
然后我按“确定”，RStudio 停止工作。我多次尝试这个。为什么这不起作用？
是将版本更改为 Base-R 的命令吗？因为我不想卸载 Microsoft R。
谢谢！

查看 R Studio 的文档，对于 Windows，R Studio 使用系统注册表确定版本，如果您在安装 MRS 并插入这些注册表项时，这可能会导致冲突。尝试重新添加 Open Source R 的注册表项，如下所示：
When you run the R installer, there are options (under ‘Select Additional
Tasks’) to ‘Save version number in registry’ and (for Administrator
installs) ‘Associate R with .RData files’.
If you tick the first option, the following string entries are added to the
Windows registry:
HKEY_LOCAL_MACHINE\Software\R-core\R\Current Version contains the version
number, currently 3.4.0.
HKEY_LOCAL_MACHINE\Software\R-core\R\[version]\InstallPath (where [version]
is currently 3.4.0) contains the path to the R home directory.
If you do not have administrative privileges on the machine while running
the installer, then the entries are created under HKEY_CURRENT_USER. The
same entries are also created under Software\R-core\R32 or Software\R-
core\R64, for 32- and 64-bit R respectively.
If you tick the second option (shown with administrative privileges only)
(‘Associate R with .RData files’) then entries are created under
HKEY_CLASSES_ROOT\.RData and HKEY_CLASSES_ROOT\RWorkspace.
After installation you can add the Registry entries by running RSetReg.exe
in a sub-folder of the bin folder, and remove them by running this with
argument /U. Note that this requires administrative privileges unless run
with argument /Personal and neither sets up nor removes the file
associations.

我认为这个答案应该可以解决您的问题：
转到 C:\Users\myaccount\AppData\Roaming\RStudio 并删除“desktop.ini.lock”文件。或重命名文件夹
