Dependencies + namespacing discipline

Defaults

• Prefer pkg::fun in package code (clear provenance, fewer NAMESPACE surprises).
• Use Imports for runtime dependencies; Suggests for tests, vignettes, optional features.
• Avoid broad imports (@import) unless there’s a strong reason.

Quick checks

devtools::check()

Common gotchas

• Using dplyr/rlang/purrr functions without namespacing causes R CMD check NOTES/ERRORS.
• Tests can use helpers from Suggests, but production code must not.
