suntools 1.0.0

Minor bugfix to maintain compatibility with CRAN Debian system

• changed timezone EET to Europe/Helsinki in tests

suntools 1.0.0

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.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
