Multi-subject cohort / study container

PhysioCohort is the multi-subject layer above PhysioLongitudinal: it holds many participants, each represented by their own longitudinal timeline of sessions, alongside a subject-level colData table (id, group/arm, diagnosis, age, sex, side, ...). This is the container a rehabilitation study needs - a cohort or the arms of a trial, as subjects x sessions - and the shape downstream pipelines, trial analyses and prognostic models iterate over (see cohortDesign).

Details

A bare PhysioExperiment / MultiRatePhysioExperiment passed as a subject is auto-wrapped into a single-session PhysioLongitudinal (visit label "session"), so cross-sectional and longitudinal cohorts share one API.

Slots

subjects: A SimpleList of named PhysioLongitudinal subjects.
colData: A DataFrame with one row per subject; a subject_id column aligns to (and is ordered as) names(subjects).
