Deletes a specific user file using the appropriate backend plugin, based
on the `ACCOUNT_BACKEND` environment variable. This function abstracts the
file removal logic, allowing different storage systems to handle file
deletion (e.g., local file system, MongoDB, Google Drive).
Usage
remove_user_file(user_id, file_name = "account_tree.Rds")
Arguments
- user_id
A character string representing the user ID.
- file_name
Name of the file to remove. Defaults to
`"account_tree.Rds"`.
Value
Invisibly returns `NULL`. Issues a warning if the file does not
exist, or throws an error if the backend plugin is not found.
Details
The actual removal behavior is implemented by the selected
backend plugin (e.g., `remove_from_file`, `remove_from_gdrive`, etc.).
Configuration is controlled via environment variables like
`ACCOUNT_BACKEND` and `ACCOUNT_BASE_DIR`.
