Changes in version 1.0.0 - Initial CRAN submission. Changes in version 0.1.0 (2026-02-04) Features - lm_sql() fits OLS linear regression models entirely in-database via a single SQL aggregation query. - Automatic dummy encoding for character and factor predictors with CASE WHEN SQL generation. - Interaction terms (*, :) fully supported, including interactions between numeric and categorical variables. - Dot expansion (y ~ .) expands to all non-response columns. - Formula transforms: I(), log(), and sqrt() translated to SQL equivalents (POWER, LN, SQRT). - Date and datetime predictor support: Date and POSIXct columns automatically converted to numeric in SQL, matching base R's lm() behavior. - Grouped regression via dplyr::group_by() computes multiple models in a single GROUP BY query. - No-intercept models (y ~ 0 + x) handled correctly. - S7-based result objects with broom::tidy() and broom::glance() methods. - orbital integration for in-database predictions. - Cholesky decomposition for matrix inversion with MASS::ginv() fallback for rank-deficient designs.
