PortfolioTesteR 0.1.4

New

• ml_backtest_multi() — run ML backtests across multiple horizons/schedules.
• pt_collect_results() — one-call collector for coverage, IC (raw & OOS-only), turnover, perf tables, and cost sweeps.
• scores_oos_only() — keep scores only on OOS decision dates.

Improvements

• Vignettes stabilized on knitr/rmarkdown (no Quarto dependency during checks).
• Expanded R/globals.R to silence data.table NSE NOTES.
• Regenerated docs with UTF-8 to avoid Non-ASCII warnings.

Compatibility

• No breaking API changes.
