Polished, Editable Tables and Statistical Results
Overview
Sends supported 'R' objects to the 'Mellio' web app and creates polished, editable statistical tables in 'R'. The 'mellio_open' interface handles common hypothesis tests, model objects, model comparisons, descriptive summaries, tabular data, plots, and image files. The 'melliotab' interface formats data frames, model summaries, correlation matrices, and side-by-side comparison tables with APA-style numeric formatting, confidence intervals, table notes, and optional significance markers. Manual table helpers can copy or save 'melliotab' output as 'HTML', 'LaTeX', or 'Markdown' when file-based handoff is needed. Payloads include package-version metadata to support reproducible reporting and software citation.
- Added Johnson-Neyman and simple-slopes support:
mellio_open()andmelliotab()now acceptjohnson_neyman()andsim_slopes()results from the 'interactions' package. Results open as a Stats card with the interval narration and a key-point table, plus a native, fully editable Johnson-Neyman figure in the web app (significance-colored slope and confidence band, interval bounds, observed moderator range, legend). - Long Mellio URLs now open through a small local redirect page. Some URL launchers (notably inside RStudio) silently truncate very long URLs, which dropped the result payload; the redirect file sidesteps the limit.
