Check attached packages

Individual session check function that inspects the attached packages. Session checkers can produce errors, warnings, or messages if requested.

Usage

check_attached_packages(action = "warn", allow_attached_packages = NULL)

Arguments

action

Behaviour to take if the status is not clean. Possible values are "error", "warn", "message", and "none". The default is action = "warn".

allow_attached_packages

Character vector containing names of packages that are "allowed", and will not trigger an action if attached to the search path.

Value

Invisibly returns an object of class sessioncheck_status.

Details

This checker inspects the list of packages that have been attached to the search path (e.g., via library()). Regardless of the value of allow, R packages that have "base" priority (e.g., base, utils, and grDevices) do not trigger an action. When allow = NULL these are the only packages that will not trigger actions.
