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

snvecR 3.10.1

• get_solution() has some examples in the README.
• Created simple vignette comparing the C- and R implementation.
• Improvements to the documentation.
• Checked test coverage to see which lines of code aren't executed during tests.

snvecR 3.10.0

• Added support for reading ZB23.Rxx and pre-computed precession-tilt solutions, e.g.: PT-ZB18a(1,1).
• snvec() now also returns column lpx by default.
• CRAN tests no longer rely on downloading the solutions.

snvecR 3.9.4

• get_solution() tests use temporary directory.

snvecR 3.9.3

• Added a package option for the cache directory.
• Set it with options(snvecR.cachedir = "/your/path").
• It still defaults to the user's cache directory.
• Made all tests, vignettes, and examples use temporary directories rather than the user's cache dir.

snvecR 3.9.2

• Made the package work for R >= 3.6.x
• added backports for tools::R_user_dir
• added GitHub CI that tests the installation on windows and mac with R 3.6.3
• Improved info messages and README

snvecR 3.9.1

• Removed a lot of dependencies
• removed all |> from functions and tests
• Should work for R < 4.0.1 now

snvecR 3.9.0

• Refactor age in ka to time in kyr throughout.
• Rename default astronomical solution from PT-ZB18a to full-ZB18a.
• For the OS, convert time to negative for consistency.
• Changed some default output! Now returns time (kyr), no longer both t and t_kyr.

snvecR 3.8.0

• Fix snapshot tests for CI (overwrite the cache dir, which is unique to each test).
• Make it possible for the user to specify a custom orbital solution as a data.frame. It should either have the same column names as the output of get_ZB18a() or as the output of orbitN; we automatically convert the column names to snvec columns names for convenience.
• Rename orbital solution to astronomical solution throughout.
• Migrate get_ZB18a to get_ZB so that the user can easily get all the Zeebe solutions from the website (and cache them as well).
• Added support for reading all Zeebe astronomical solutions to function get_solution(). Also a added a wrapper for astrochron::getLaskar() if the user provides a supported Laskar solution name.

snvecR 3.7.7

• Fix CRAN issues by revising the logic for checking the cache.

snvecR 3.7.6

• Remove cache directory after last example (even though it's in a donttest environment).

snvecR 3.7.5

• Added a NEWS.md file to track changes to the package.
• Note: version number is consistent with snvec C package.
• Implemented first public version based on C-code in Zeebe and Lourens 2022, as explained .
• Added snvec() function that does all the work.
• Added ZB18a dataset with orbital solution.
• Added tests using testthat.
• Added snvec() output parameter with choice to select "ode", "all", or "nice" (default).
• Added a vignette with a grid of variations on Td and Ed.
• Added a bookdown website rendering.
• Released a version to Zenodo and assigned a doi.
• Removed ZB18a dataset from the package because it was too large.
• Added functions get_solution, get_ZB18a, prepare_solution.
• Added caching code for the orbital solution.
• Remove the cache directory after running tests, so that reproducible environments remain clean.
