Problem Researchers often need to create new categorical variables based on conditions from existing variables (e.g., grouping a numeric variable into bands). Currently, this requires writing conditional JavaScript, such as: if (sumCola < 5) 1; else if (sumCola >= 5 && sumCola <= 10) 2; else if (sumCola > 10) 3; else NaN; This creates a barrier for non-technical users and increases the likelihood of syntax errors. Proposed Feature Introduce a point-and-click interface for creating new categorical variables using logical conditions. What It Should Do: * Allow users to select an existing variable * Define conditions using dropdowns (e.g., <, <=, >, between) * Add multiple condition rows visually * Automatically assign category values and labels * Generate the underlying logic without requiring JavaScript Impact: * Removes reliance on code * Reduces errors *Makes variable creation faster and more accessible for all researchers
