nhanesdata v0.2.1

CRAN submission candidate (Feb. 18, 2026)

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 v0.2.0

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.
