First release of suntools package on CRAN. Provides a
set of functions to calculate sun position, sunrise, sunset, solar noon
and twilight, which were formerly made available by the
[maptools]((https://CRAN.R-project.org/package=maptools) package.
New features
- core functionality from former
maptools/R/sun-methods.R
has been retained in the original form.
- new method for spatial objects of class
sf
- each method / function moved into a separate file for better
readability.
- The package now includes unit tests to ensure reliability of
functions.
- CI/CD has been introduced via GitHub Actions for a more efficient
workflow. This includes automated checks that run across different
operating systems (macOS, Windows, Ubuntu) and R versions.
- Added a
NEWS.md file to track changes to the
package.
Bug Fixes
- Resolved an issue where functions in the package would return a
dataframe with a row name “newlon” when inputting a single-row matrix.
This was unexpected and appeared in R versions < 4.3.0.
- Resolved an issue where functions in the package would return
numeric values instead of dataframes.
