Changes in version 1.0.3 (2024-11-22) - Fixed CRAN check note missing package anchor for package deSolve in the documentation of setup_statevars(). - In the output of fuel_and_co2_evaluation(), the variable name co2_road_maint_total_l has been corrected to co2_road_maint_total_kg. I.e. the variable name now contains the correct unit (kg). Changes in version 1.0.2 (2024-06-04) - The authors have published an article that explains the science behind the package in detail. We have inserted links to this article (open access) in the README file and in the vignette. The article is available online here: https://www.sciencedirect.com/science/article/pii/S0168169924004824.
