surveyPrev 2.0.0 (2026-06-19)

Indicators

• Significantly expanded indicator support (now 183 indicators in the new indicatorList dataset), covering mortality, antenatal/postnatal and delivery care, family planning, child nutrition/vaccination, malaria, WASH, wealth, education, and FGM chapters.
• Indicator functions renamed to standardized DHS recode codes,
  with legacy exported functions removed. The surveyPrevIndicators dataset is replaced by indicatorList.
• Added 2-year and 5-year "preceding survey" variants for many indicators, plus many country/survey-specific fixes.
• addNewIndicator() to register a user-defined processing function.

Models

• Child mortality support (U5MR, IMR, NMR) for direct, Fay-Herriot, and cluster-level models, using person-month formatting via getBirths().
• Variance adjustment for direct estimates with sparse data.
• Area-level covariates via getCovariate(), unit-level covariates and nested models in clusterModel(), and Admin1 × urban/rural stratification.
• Direct estimates and cluster models can return posterior samples.

Data download & spatial input

• getDHSdata() gains a SurveyType argument (DHS/SPE) and handles surveys with multiple datasets.
• geoBoundaries support as an alternative to GADM (get_geoBoundaries(), addUpper()).
• clusterInfo() now flags invalid GPS, points outside boundaries from jittering, and Admin1/Admin2 mismatches (wrong.points); poly.adm2 may be NULL.

Visualization

• New plotting functions: interactive leaflet maps (prevMap.web()), static maps, exceedance-probability maps, rank plots, and interval plots (Admin 2 grouped by Admin 1, multi-model comparison).

Output & infrastructure

• Standardized output columns and a unified cv definition
• Reduced dependencies and CRAN-readiness fixes.
• Updated vignettes/examples.
