Versioned sampling-design declaration — SamplingDesign-class • landscapeR

A SamplingDesign object is a lightweight, versioned declaration that travels with a StateTransitionData container. It describes how samples were collected (cross-sectional, independent over observed time, or longitudinal) and names the colData columns that carry subject identity and ordered time when applicable.

Details

Users construct designs with cross_sectional, independent_time_course, or longitudinal. The "unspecified" kind is created only by the schema migration machinery (see R/03-container.R).
