trace_model_to_evidence: Convert Trace Model to R4SUB Evidence

In r4subtrace: Traceability Engine for Clinical Submission Readiness

Convert Trace Model to R4SUB Evidence

Description

Emits evidence rows compatible with r4subcore::validate_evidence() for each ADaM variable's trace level, plus diagnostic rows for orphans, ambiguities, and conflicts.

Usage

trace_model_to_evidence(
  trace_model,
  ctx,
  source_name = "r4subtrace",
  source_version = NULL
)

Arguments

trace_model	A trace_model object from build_trace_model().
ctx	An r4sub_run_context from r4subcore::r4sub_run_context().
source_name	Character; the name of the evidence source.
source_version	Character or NULL; version of the source.

Value

A data.frame of evidence rows passing r4subcore::validate_evidence().

Examples

library(r4subcore)
ctx <- r4sub_run_context(study_id = "TEST001", environment = "DEV")
adam_meta <- data.frame(
  dataset = "ADSL", variable = c("STUDYID", "AGE"),
  label = c("Study ID", "Age")
)
sdtm_meta <- data.frame(
  dataset = "DM", variable = c("STUDYID", "AGE"),
  label = c("Study ID", "Age")
)
map <- data.frame(
  adam_dataset = "ADSL", adam_var = c("STUDYID", "AGE"),
  sdtm_domain = "DM",   sdtm_var = c("STUDYID", "AGE")
)
tm <- build_trace_model(adam_meta, sdtm_meta, mapping = map)
ev <- trace_model_to_evidence(tm, ctx = ctx)
r4subcore::validate_evidence(ev)
