renv (version 1.0.11)

clean: Clean a project

Description

Clean up a project and its associated R libraries.

Usage

clean(project = NULL, ..., actions = NULL, prompt = interactive())

Value

The project directory, invisibly. Note that this function is normally called for its side effects.

Arguments

project

The project directory. If NULL, then the active project will be used. If no project is currently active, then the current working directory is used instead.

...

Unused arguments, reserved for future expansion. If any arguments are matched to ..., renv will signal an error.

actions

The set of clean actions to take. See the documentation in Actions for a list of available actions, and the default actions taken when no actions are supplied.

prompt

Boolean; prompt the user before taking any action? For backwards compatibility, confirm is accepted as an alias for prompt.

Actions

The following clean actions are available:

package.locks

During package installation, R will create package locks in the library path, typically named 00LOCK-<package>. On occasion, if package installation fails or R is terminated while installing a package, these locks can be left behind and will inhibit future attempts to reinstall that package. Use this action to remove such left-over package locks.

library.tempdirs

During package installation, R may create temporary directories with names of the form file\w{12}, and on occasion those files can be left behind even after they are no longer in use. Use this action to remove such left-over directories.

system.library

In general, it is recommended that only packages distributed with R are installed into the default library (the library path referred to by .Library). Use this action to remove any user-installed packages that have been installed to the system library.

Because this action is destructive, it is by default never run -- it must be explicitly requested by the user.

unused.packages

Remove packages that are installed in the project library, but no longer appear to be used in the project sources.

Because this action is destructive, it is by default only run in interactive sessions when prompting is enabled.

Examples

if (FALSE) {

# clean the current project
renv::clean()

}
