Validate Trace Mapping

Source: R/validate_inputs.R
validate_mapping.Rd

Checks that a mapping data.frame contains the required columns (adam_dataset, adam_var, sdtm_domain, sdtm_var) and canonicalizes names, trims whitespace, and optionally uppercases dataset/domain names.

Usage

validate_mapping(df, uppercase_datasets = TRUE)

Arguments

df

A data.frame describing ADaM-to-SDTM variable mappings.

uppercase_datasets

Logical; if TRUE, uppercases adam_dataset and sdtm_domain. Default TRUE.

Value

A tibble with canonicalized column names and values.

Examples

map <- data.frame(
  ADAM_DATASET = "adsl", ADAM_VAR = "AGE",
  SDTM_DOMAIN = "dm", SDTM_VAR = "AGE"
)
validate_mapping(map)
