colSums.ena.matrix

This S3 method computes column sums for ENA matrix objects, with optional binarization. It is used to summarize connection counts across rows (e.g., for each unit or context).

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>.

colSums.ena.matrix function

<dl><dt>x</dt>
<dd>An object of class "ena.matrix" (or compatible matrix/data.frame) containing connection data.</dd>
<dt>na.rm</dt>
<dd>Logical; whether to remove missing values (passed to `colSums`).</dd>
<dt>dims</dt>
<dd>Integer; which dimensions to sum over (passed to `colSums`).</dd>
<dt>binary</dt>
<dd>Logical; if TRUE, binarizes the matrix before summing (i.e., all nonzero values become 1).</dd></dl>
