surveyframe - Survey Instrument Workflows

Provides a design-first survey research workflow. An instrument, an analysis plan declared before data collection, and a measurement or structural model are held together in one typed, integrity-checked object (the 'sframe'), so a study's confirmatory tests are fixed before responses arrive rather than chosen afterward. Includes visual instrument design via a browser-based builder or 'Shiny' studio, export to a self-contained static HTML survey, an embeddable 'Shiny' module, SHA-256 integrity-checked serialisation to the '.sframe' format, multi-page survey rendering with branching logic, response quality checking, scale scoring, psychometric diagnostics, analysis-plan execution, model syntax generation for EFA, CFA, CB-SEM, and PLS-SEM, an interactive response dashboard, codebook generation, and reproducible HTML reporting. Also supports multi-criteria decision analysis (AHP, ANP, DEMATEL, TOPSIS, VIKOR, MOORA, SMART, WASPAS, PROMETHEE II, ELECTRE I), small-sample survey helpers, and text and open-ended response analysis (term and n-gram frequency, keyword in context, co-occurrence and co-occurrence networks, sentiment, document-feature matrices, and topic modelling via LDA or structural topic models).
