Package: astronomyengine Title: R Bindings to the 'Astronomy Engine' C Library Version: 0.1.0.9000 Authors@R: c(person(given = "Mitchell", family = "O'Hara-Wild", email = "mail@mitchelloharawild.com", role = c("aut", "cre"), comment = c(ORCID = "0000-0001-6729-7695")), person(given = "Don", family = "Cross", role = c("aut", "cph"), comment = "Author of the bundled Astronomy Engine C library")) Description: Provides access to the 'Astronomy Engine' C library () by Don Cross. The library calculates positions of the Sun, Moon, and planets, and predicts astronomical events such as rise/set times, lunar phases, equinoxes, solstices, eclipses, and transits. It is based on the 'VSOP87' planetary model and is accurate to within approximately one arcminute. This package bundles the single-file C source so that other R packages can link against it via 'LinkingTo' without shipping their own copy.
