Overview of the 'Unable to Move Temporary Installation' Error
The 'Unable to Move Temporary Installation' error is a common issue when trying to install packages in R. This error occurs when R is unable to move the temporary installation files to their proper location. The main reasons for this error are:
- Insufficient permissions to write or modify files in the library directory.
- The target library directory is locked or being used by another application.
Step-by-Step Solution to Fix the Error
Here is a step-by-step guide to fixing the 'Unable to Move Temporary Installation' error in R:
Step 1: Run R or RStudio as an Administrator
Running R or RStudio with administrator privileges can help address any permission issues that might be causing this error. To do this, follow these steps:
- Right-click on the R or RStudio icon.
- Select 'Run as administrator'.
- Confirm your selection if prompted.
Step 2: Unlock the Library Directory
Ensure that there are no applications or processes currently accessing the library directory. You can do this by closing all other applications that might be using the directory, such as file explorers or other R sessions.
Step 3: Install the Package in a User-Writable Library
If you still face the error after trying the above steps, you can try installing the package in a user-writable library. To do this:
- Create a new folder for your user-specific library, e.g.,
C:\Users\YourUsername\R\library. - Run the following command in R to add the new library path:
.libPaths(c("C:/Users/YourUsername/R/library", .libPaths()))
- Install the package using
install.packages(), specifying the new library path:
install.packages("package_name", lib = "C:/Users/YourUsername/R/library")
FAQs about the 'Unable to Move Temporary Installation' Error
1. Can I avoid this error by installing packages from a different source?
While the error is not necessarily tied to a specific package source, it is usually related to the library directory and permissions. Regardless of the package source, you might still encounter the error if the underlying issue persists.
2. How do I check if the library directory is locked?
One way to check if the library directory is locked is by trying to create a new file or folder within the directory. If you can create a new file or folder without any issues, the directory is likely not locked.
3. Can I specify a custom library path when installing packages in R?
Yes, you can specify a custom library path when installing packages using the install.packages() function. Just provide the lib argument with the desired library path, like so: install.packages("package_name", lib = "path/to/your/library").
4. Can I change the default library directory in R permanently?
Yes, you can modify the R_LIBS_USER environment variable in your .Renviron or .Rprofile file to change the default library directory permanently. Add the following line to the respective file:
R_LIBS_USER="C:/Users/YourUsername/R/library"
5. How do I know if I have sufficient permissions to write or modify files in the library directory?
To check if you have sufficient permissions, try creating a new file or folder within the library directory. If you can do so without any issues, you likely have the necessary permissions.
