3 Dataset Catalog and Provenance🔗ℹ

The following catalog is generated from the same registry used by dataset-info. Column order matches the full table returned by load-dataset-table. All 13 datasets are bundled with the package.

Redistribution follows upstream distribution terms: R data under GPL-2 or GPL-3, lars diabetes under GPL-2, and UCI data under CC BY 4.0. This records the redistribution basis, without asserting independent original-owner permission. Code is Apache-2.0 OR MIT. Full license texts and upstream variable descriptions and citations are bundled in datasets/licenses and datasets/provenance. The maintainer importer pins source archives by SHA-256. Normalized checksums cover the exact UTF-8 bytes of each .rktd file. Historical observations are not silently corrected except for choosing the documented corrected UCI Iris variant.
