It provides\nexplicit steps to turn variables into states, states into\naligned sequences, and sequences into trajectory groups,\nfollowed by tidy trajectory descriptions. A single call runs\nthe complete analysis with transparent, overridable automation\nof data roles and cluster counts, and an evaluation verb\ncompares the fitted clustering against its alternatives.\n'Nestimate' provides the default sequence-clustering backend\nand all sequence plots.

by\n state, one panel per time point, or a single pooled panel with\n by_time = FALSE.\n- state_descriptives(): per-state, per-indicator summary (n, mean, sd,\n median, range), optionally per time point and on the original scale.\n- evaluate() plots colour the state row with the fit's state_colors so it\n matches the other state plots; the trajectory row keeps a distinct palette.\n- Combined per-trajectory grid widens the distribution column for its y-axis.\n\nArticles and docs:\n- New \"Standardization\" article, opening on the nested structure of\n longitudinal data.\n- Clustering-algorithms article gains an SVG taxonomy diagram.\n- Simplify vignette fits to the automatic defaults unless an argument is\n being illustrated; drop apply-family scaffolding.\n- Add inst/CITATION (method paper plus the software).\n\nMetadata:\n- Bump to 0.4.0; add author email.\n", "time": 1787656969 }, "_maintainer": { "name": "Mohammed Saqr", "email": "saqr@saqr.me", "login":
