growR 1.2.0
CRAN release: 2023-12-14
Added
- Green biomass has a lower bound defined by a minimum grass height. This is to prevent the population from completely dying out and effectively simulates reserves.
Changed
- The start of the growing season is now determined by the multicriterial thermal definition as described in chapter 2.3.1.3 of the dissertation of Andreas Schaumberger: Räumliche Modelle zur Vegetations- und Ertragsdynamik im Wirtschaftsgrünland, 2011, ISBN-13: 978-3-902559-67-8
Removed
- compare.R script is not fetched by
setup_directory()
.
growR 1.1.0
CRAN release: 2023-11-22
Added
Input integrity checking for WeatherData and ManagementData.
PScanPlotter (
plot_parameter_scan
) now allows to select which variable to display (from dBM, cBM and cBM_tot).Instances where simulation results for variable
dBM
are visualized or compared to experimental data now allow specifying and integration window fordBM
, which should be set to match the experimental reality. This concernsModvegeSite$plot()
andanalyze_parameter_scan()
as well as thecompare.R
script.S3 dispatch for plot method of
ModvegeSite
objects ->plot(mvs)
is now possible ifmvs
is aModvegeSite
instance.ParameterData
input checking: throws error on duplicate input parameter name.Debug utility conveniences
browse
andbrowse_end
.ModvegeSite$plot_XXX
functions for more insights into model behaviour, with XXX inwater
,limitations
,growth
andplot_var
for generic variable plotting.
Changed
Input data CSV files are now actual CSV files, instead of “semicolon-separated value” files.
ParameterData
now assumes default values for most parameters.check_parameters
now only throws an error if any of the really
required parameters are missing.Number of days per year is now inferred from weather data instead of hardcoded to 365, allowing simulations to be run for years with incomplete data.
Crop coefficient (
parameters$crop_coefficient
) and senescence capping are now model parameters instead of being hardcoded.
