healthbR 0.1.1

Changes

• Moved arrow package from Imports to Suggests for better cross-platform compatibility. The package now checks for arrow availability and provides informative error messages with installation instructions when needed.

• Added cache_dir parameter to all data fetching functions (vigitel_data(),

  vigitel_download(), vigitel_variables(), vigitel_dictionary(), vigitel_cache_status(), vigitel_clear_cache()). This allows using tempdir() for temporary storage that doesn’t persist after the R session.

• Updated examples to use cache_dir = tempdir() to avoid leaving files on the system during CRAN checks.
