units

Internal helper to initialize and label units of analysis in a TMA model object.
Given a data.frame and a set of columns, this function creates a model structure
with unit labels and context placeholders for each unique unit.

A robust computational framework for analyzing complex multimodal data. Extends existing state-dependent models to account for diverse data streams, addressing challenges such as varying temporal scales and learner characteristics to improve the robustness and interpretability of findings. For methodological details, see Shaffer, Wang, and Ruis (2025) "Transmodal Analysis" <doi:10.18608/jla.2025.8423>.
