snvecR: Calculate Earth’s Obliquity and Precession in the Past

Description

Easily calculate precession and obliquity from an orbital solution (defaults to ZB18a from Zeebe and Lourens (2019) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1126/science.aax0612")}) and assumed or reconstructed values for tidal dissipation (Td) and dynamical ellipticity (Ed). This is a translation and adaptation of the 'C'-code in the supplementary material to Zeebe and Lourens (2022) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1029/2021PA004349")}, with further details on the methodology described in Zeebe (2022) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.3847/1538-3881/ac80f8")}. The name of the 'C'-routine is 'snvec', which refers to the key units of computation: spin vector s and orbit normal vector n.
