Export Trial Analysis Sets to ADaM-Shaped Data

Source: R/cdisc.R
toADaM.Rd

Builds an ADSL population table and a generic BDS analysis table from explicit analysis sets. This structural export is not a claim of formal ADaM conformance.

Usage

toADaM(
  set,
  subject_data,
  bds = NULL,
  study_id = set$trial_id,
  id_col = "id",
  treatment_col = "arm",
  population_flags = NULL
)

Arguments

set

The authoritative primary analysis_set.

subject_data

One row per source participant.

bds

Optional generic BDS source data frame. A named list may contain an ADBDS source plus already constructed analysis datasets such as ADQS.

study_id

Non-empty study identifier.

id_col, treatment_col

Subject ID and originally assigned treatment columns.

population_flags

Optional named list of other analysis_set objects from the same source population.

Value

An adam_export containing datasets, manifest, and population metadata.

Examples

trial <- Trial("T1", c("active", "control"))
subjects <- data.frame(
  id = c("p1", "p2", "screen"),
  arm = c("active", "control", NA),
  randomized = c(TRUE, TRUE, FALSE)
)
itt <- intentionToTreat(trial, subjects)
export <- toADaM(itt, subjects)
export$datasets$ADSL
