Diagnose Unrestored Environment Variables — lab_sys_setenv • checktor

Flags Sys.setenv() with no matching cleanup in the same function.

Usage

lab_sys_setenv(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

No clause names environment variables, but they are session state exactly as options() are, so the same restore-on-exit requirement applies. The CRAN Cookbook states it for options under Change of Options, Graphical Parameters and Working Directory. See vignette("check-sources", package = "checktor") for how every check maps to its source.

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