Provides a design-matched coverage check that simulates validation configurations on the user''s own design and at the signal-to-noise ratio of the fitted surfaces, an equivalence test for alignment of optima, local Gaussian and mean curvature, and a surface-area ratio. Includes the Drosophila lifespan and fecundity dataset of Lee et al. (2008) "Lifespan and reproduction in Drosophila: new insights from nutritional geometry" as a worked example. The angular approach was introduced in Morimoto (2023) "Nutrigonometry I: using right-angle triangles to quantify nutritional trade-offs in performance landscapes" .' authors: - family-names: Morimoto given-names: Juliano email: juliano.morimoto@abdn.ac.uk orcid: https://orcid.org/0000-0003-3561-1920 repository: https://jmor2753.r-universe.dev repository-code: https://github.com/jmor2753/nutrigon commit: bd9496233cc3d033ceb718d525476f3b41893038 url: https://github.com/jmor2753/nutrigon date-released: '2026-10-23' contact: - family-names: Morimoto given-names: Juliano email: juliano.morimoto@abdn.ac.uk orcid: https://orcid.org/0000-0003-3561-1920
