chmsflow 0.1.0

Basic features

• Added variables.csv that contains list of CHMS variables in chmsflow.
• Added variable-details.csv that maps variables across CHMS cycles 1-6
• Added Vignettes to describe the process of using rec_with_table() (part of recodeflow) to combine the data

Medication features

• recode_meds_cycles1to2() and recode_meds_cycles3to6() recode medication data and merge medication columns into the main cycle data frame in one call. Both share the same call signature, so the workflow is identical regardless of cycle:

  cycle1 <- recode_meds_cycles1to2(cycle1, cycle1_meds, c("any_htn_med", "diab_med"))
  cycle3 <- recode_meds_cycles3to6(cycle3, cycle3_meds, c("any_htn_med", "diab_med"))

• aggregate_meds_by_person() collapses long-format medication data to one row per respondent, preserving tagged_na("a") (valid skip) and tagged_na("b") (missing) distinctions across the aggregation.

• recode_after_meds() recodes derived variables (e.g. htn_status, diab_status) whose inputs include pre-computed medication variables, automatically excluding meds-database rows from variable_details so medication columns are passed through rather than re-derived from raw ATC/MHR columns.

• 16 ATC-classification functions (is_ace_inhibitor(), is_beta_blocker(), is_calcium_channel_blocker(), is_diuretic(), is_diabetes_med(), is_nsaid(), is_any_antihtn_med(), is_other_antihtn_med(), plus their is_*_cycles1to2() variants) are exported for custom workflows.

• New vignette recoding_medications.qmd documents the medication-recoding workflow for both cycle groupings, with a section on calling the underlying is_* classifiers directly.

Breaking changes (medications)

• The any_htn_med2 argument of derive_hypertension(), derive_hypertension_adj(), derive_hypertension_control(), and derive_hypertension_control_adj() has been renamed to any_htn_med. The diab_med2 argument of derive_diabetes_status() has been renamed to diab_med. Calls that pass the old argument by name will fail with an “unused argument” error.
• The self-referential any_htn_med2 and diab_med2 entries in inst/extdata/variable-details.csv have been removed. New any_htn_med and diab_med entries cover all six cycles via three database tiers: DerivedVar rows for cycles 1-2 (atc_*/mhr_* columns), DerivedVar rows for cycles 3-6 (meucatc, npi_25b), and copy passthrough rows for the main cycle databases once medications have been merged in.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
