4 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. It lists every registry installed when this manual was built, one section per package.

Redistribution follows upstream distribution terms. Each package section lists its data licenses and each entry names its own: in datasets-core, 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 for datasets-core, and in licenses and provenance beside the registry of any other package. The maintainer importer pins source archives by SHA-256. Normalized checksums cover the exact UTF-8 bytes of each dataset’s uncompressed .rktd content. Historical observations are not silently corrected except for choosing the documented corrected UCI Iris variant.
