spec_standard: The CDISC standard a spec implements

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

The CDISC standard a spec implements

Description

Return the one CDISC standard the specification carries (e.g. "ADaMIG 1.1", "SDTMIG 3.2"). A artoo_spec is single-standard by construction — artoo_spec() aborts when its sources mix standards — so this is always a scalar; NA when no source named one.

Usage

spec_standard(spec)

Arguments

spec	The specification to read. ⁠<artoo_spec>: required⁠.

Value

A ⁠<character(1)>⁠: the standard, or NA when unspecified.

See Also

spec_study() for the rest of the study-level metadata; artoo_spec() for how the standard is resolved.

Examples

# ---- Example 1: the standard set at construction ----
#
# Pass the standard explicitly (or let it resolve from a P21 workbook's
# Standard column / a Define-XML study block) and read it back.
spec <- artoo_spec(
  cdisc_adam_datasets, cdisc_adam_variables,
  codelists = cdisc_codelists,
  standard = "ADaMIG 1.1"
)
spec_standard(spec)

# ---- Example 2: unspecified resolves to NA ----
#
# A spec built without any standard source carries NA.
bare <- artoo_spec(
  cdisc_adam_datasets, cdisc_adam_variables,
  codelists = cdisc_codelists
)
spec_standard(bare)
