PNADCperiods 0.1.2

CRAN policy compliance (response to Brian Ripley, 2026-04-26)

• Internet-using functions now fail gracefully with an informative message() (no warning(), no stop()) and return NULL invisibly when the SIDRA API is unreachable or returns an unexpected schema. Affects fetch_monthly_population(), fetch_sidra_rolling_quarters(), and pnadc_apply_periods() (which falls back to returning the data with the crosswalk applied but no calibrated weights when SIDRA is unavailable).
• New mocked-API tests (testthat::local_mocked_bindings) verify the graceful-failure behaviour offline.
• Test suite no longer depends on the SIDRA API: 22 calibration and pipeline tests now use locally-constructed target_totals mocks instead of fetching live SIDRA population data.

Bug fixes — mensalize_sidra_series()

• Trailing NA in the rolling-quarter input (e.g., when IBGE has published IPCA/INPC for a month but not yet the corresponding PNADC rolling quarter) no longer produces phantom mensalized values that silently echoed the value of the same mesnotrim position three months earlier. The mask now zeros out only trailing positions after the last observed rq, leaving leading positions intact.
• IPCA lag is pre-computed before the PNADC filter is applied, removing contamination of starting points by future-IPCA observations.
• INPC lag is pre-computed in compute_series_starting_points(), with test coverage for derived-series propagation through aggregates.

Documentation

• README, vignettes and pkgdown navbar updated to recommend install.packages("PNADCperiods") now that the package is on CRAN.

PNADCperiods 0.1.1

CRAN resubmission

• Expanded all acronyms in DESCRIPTION (IBGE, SIDRA, UPA, API)
• Added Hecksher (2020) reference with URL
• Replaced \dontrun{} with \donttest{} for API examples; created runnable examples for validate_pnadc() and get_sidra_series_metadata()
• Fixed missing anchor parameter in compute_starting_points_from_microdata()
• Removed .onLoad that globally set data.table thread count
• Added skip_on_cran() to all API-dependent tests
• Added fst to Suggests

PNADCperiods 0.1.0

Initial CRAN release

Microdata period identification

• pnadc_identify_periods(): Build crosswalk mapping survey observations to months, fortnights, and weeks using IBGE’s technical break rules and respondent birthdates.
• pnadc_apply_periods(): Apply crosswalk and calibrate weights to SIDRA population totals with adaptive hierarchical cell definitions.
• pnadc_experimental_periods(): Probabilistic assignment and UPA aggregation strategies for improved fortnight/week determination rates.
• validate_pnadc(): Input validation for required PNADC variables.

SIDRA mensalization module

• get_sidra_series_metadata(): Metadata for 86+ PNADC rolling quarter series available from the IBGE SIDRA API.
• fetch_sidra_rolling_quarters(): Download rolling quarter data from SIDRA.
• mensalize_sidra_series(): Convert rolling quarter series into exact monthly estimates via matrix inversion, without requiring microdata access.
• fetch_monthly_population(): Fetch monthly population totals from SIDRA.
• compute_starting_points_from_microdata(): Compute y0 starting points for the mensalization algorithm from survey microdata.
