Diagnose Hardcoded Seed Setting — lab_seed

Flags set.seed(<numeric>) calls. Multi-line forms are handled because the check matches the call AST node, not raw text.

Usage

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

Arguments

path: Character. Path to package directory.
verbose: Logical. Print diagnostic messages.
parsed: Internal. Pre-parsed source cache; if NULL, files are read from path on demand.

Value

checktor_check_result() with passed, issues, message.

Source

The CRAN Repository Policy asks a package not to modify the user's workspace, and set.seed() writes .Random.seed there, changing the random-number stream for the rest of the session. See vignette("check-sources", package = "checktor") for how every check maps to its source.

Examples

pkg <- example_diagnose_scenario("code_examples/seed_setting_bad.R",
                                 show_content = FALSE)
lab_seed_setting(pkg, verbose = FALSE)   # prints PASSED/FAILED
#> ✖ Seed setting check: FAILED
#> Issues found:
#> • seed_setting_bad.R:7
