Remove User-Installed Packages

Source: R/remove_user_installed_packages.R
remove_user_installed_packages.Rd

Identifies and removes all user-installed R packages from the system, while carefully preserving base and recommended packages, as well as packages installed in specific system libraries (e.g., MRO).

Usage

remove_user_installed_packages()

Value

Invisibly returns a named list with components: status ("done" or "clean") and packages_removed (character vector).

Details

The function performs the following steps:

  1. Retrieves a list of all installed packages.

  2. Filters out packages located in libraries containing "MRO" to avoid corrupting system-specific installations.

  3. Filters out packages with a priority of "base" or "recommended" to ensure core R functionality remains intact.

  4. Identifies the library paths where the remaining user packages are installed.

  5. Iteratively removes each identified user package using `remove.packages()`.

Warning

This function modifies files on disk or the global environment. Please ensure you have a backup or are using version control (e.g., Git) before execution.
