cdisc_spec: CDISC demo specification tables (one standard per pair)

In artoo: Lossless CDISC-Native Input and Output for Clinical Datasets

CDISC demo specification tables (one standard per pair)

Description

The constructor-shaped metadata tables for the bundled demo data, split by CDISC standard because a artoo_spec carries exactly one: cdisc_adam_datasets + cdisc_adam_variables describe ADSL (ADaMIG 1.1), and cdisc_sdtm_datasets + cdisc_sdtm_variables describe DM (SDTMIG 3.1.2). Each variables table is derived from the data (names, labels, inferred CDISC types, byte lengths) by ⁠data-raw/⁠. Pass one standard's pair to artoo_spec(); passing both pairs together aborts with artoo_error_spec — mixing standards in one spec is the mistake the split exists to prevent.

Usage

cdisc_adam_datasets

cdisc_adam_variables

cdisc_sdtm_datasets

cdisc_sdtm_variables

cdisc_codelists

Format

Each ⁠*_datasets⁠ table is a data frame with one row per dataset:

dataset

Dataset name ("ADSL" or "DM").

label

Dataset label.

standard

The CDISC standard, consumed into the spec's spec_standard().

Each ⁠*_variables⁠ table is a data frame with one row per variable:

dataset

Owning dataset name.

variable

Variable name.

label

Variable label (from the data's label attribute).

data_type

CDISC dataType inferred from the column's class.

length

Storage length (max byte width for character, 8 for numeric).

order

Variable order within the dataset.

codelist_id

NCI codelist reference ("C66731" on SEX).

cdisc_codelists is a data frame of controlled-terminology terms (the real NCI codelist C66731 for SEX):

codelist_id

Codelist identifier ("C66731").

term

Submission value ("M", "F", ...).

decode

Decoded value ("Male", "Female", ...).

order

Term order.
