Supports\nuser-defined target functionals and directed acyclic graphs of\nnuisance learners with per-node training fold widths,\ntarget-specific evaluation windows, and fold-allocation modes\n(\"overlap\", \"disjoint\", \"independence\"). Returns either numeric\nestimates (mode = \"estimate\") or cross-fitted prediction\nfunctions (mode = \"predict\"), with configurable aggregation\nover panels and repetitions, reuse-aware caching, and failure\nisolation, making it well-suited for simulation studies and\nlarge benchmarks.", "License": "GPL-3", "URL": "https://github.com/EtiennePeyrot/crossfit-R", "BugReports":
