nhanesdata 0.2.2 (2026-05-04)
Bug Fixes
- Fixed
create_design() crash for any analysis including 1999 or 2001
NHANES cycles. The needs_2yr flag was referenced but never defined,
causing object 'needs_2yr' not found at runtime.
- Fixed
create_design() requiring 2-year weight columns (wtint2yr,
wtmec2yr) for datasets containing only 1999/2001 cycles, where those
columns do not exist in NHANES demographic files.
- Fixed fasting weight validation to check for
wtsaf4yr when 1999/2001
cycles are present, matching the calculation logic that already used it.
- Added
wtsaf4yr to globalVariables() to resolve R CMD check NOTEs.
- Corrected roxygen documentation that incorrectly stated 4-year fasting
weights were not supported.
nhanesdata 0.2.1 (2026-02-28)
Bug Fixes
- Converted vignettes from Quarto (.qmd) to R Markdown (.Rmd) to fix
vignette build failures on Windows CI.
New Features
- Adding
create_design() function to return survey-weighted design data
for use in downstream analyses. Combines cycles and properly accounts
for weight type (interview, MEC, fasting) and adheres to CDC guidelines
for use with earlier cycles. See CDC Weighting Guidelines
for more information.
nhanesdata 0.2.0
Released: Feb. 2026
Breaking Changes
- Categorical columns across all datasets are now stored as character with
human-readable labels instead of raw numeric codes. For example, BMX
bmdbmic values like 2, 3, 4, 1 are now "Normal weight",
"Overweight", "Obese", "Underweight". This affects 95 variables
across 22 datasets.
Bug Fixes
- Fixed data corruption where factor-to-numeric conversion returned internal
level indices instead of actual CDC codes (e.g., codes
1, 3, 4 were
silently stored as 1, 2, 3).
- Fixed continuous variables like
ridageyr and indfmpir being corrupted
when categorical label mappings were incorrectly applied to them.
- Fixed column type clashes when binding survey cycles where a column existed
in some cycles but not others.
New Features
- Cross-cycle label translation: when the CDC codebook is unavailable for a
particular cycle, labels are now carried over from a sibling cycle so all
waves have consistent human-readable values.
- Added 5 new datasets:
dxxag, l10, l10am, lab10, lab10am
(71 datasets total).
- Added
inst/CITATION for citation("nhanesdata") support.
Contributors
- Added Amrit Baral, Natalie Neugaard, Johannes Thrul, and Janardan Devkota
as contributors.
nhanesdata 0.1.1
Released: Jan. 2026
Changes
- Automated annual data updates via GitHub Actions with checksum-based
change detection and Cloudflare R2 uploads.
- Replaced
pins with direct R2 uploads for simpler URL structure.
- Added dataset catalog vignette with searchable table.
nhanesdata 0.1.0
Breaking Changes
read_r2() renamed to read_nhanes().pull_nhanes() no longer exported; use read_nhanes() to load data.
Improvements
- Reduced required dependencies (moved 7 packages to Suggests).
- Dataset names are now case-insensitive.
- Improved error messages and
get_url() reliability.
Bug Fixes
- Fixed
pull_nhanes() where save() failed with "object not found" error.
- Fixed NULL handling in
term_search() and var_search().
- Fixed
Begin.Year column not converting to numeric.
nhanesdata 0.0.0.9000
- Initial development version with core functionality for accessing and
managing NHANES data.
