Diagnose Changes to options(warn=) — lab_warn_option • checktor

Flags a change to options(warn = ) that is not restored.

Usage

lab_warn_option(path, verbose = TRUE, parsed = NULL)

Arguments

path: Character. Path to the package directory. Default: ".".
verbose: Logical. Print diagnostic output. Default: TRUE.
parsed: Optional pre-parsed source, as returned internally by the orchestrator. Defaults to parsing path afresh.

Value

checktor_check_result() with passed, issues, message.

Source

The CRAN Cookbook covers this under Setting options(warn = -1). Suppressing warnings for the rest of the session hides them from everything that runs afterwards, so restore the previous value via on.exit(). See vignette("check-sources", package = "checktor") for how every check maps to its source.

checktor(), which runs this and every other check.
