growR 1.3.0
CRAN release: 2024-05-23
Added
- An additional option for determination of growing season start is available through
ModvegeSite$set_SGS_method. This comes with a different available definition of the temperature sum and is reflected in the new methodsstart_of_growing_season,start_of_growing_season_mtd,weighted_temperature_sum`.
Changed
-
j_start_of_growing_seasonis written to output file headers. - Output file header contains
cut_DOYs. -
growR_run_loopallows use of previous year’s state variables as initial conditions for current year by means of theindependentargument. -
stubble_heightis now a parameter (i.e. a field ofModvegeParameters) instead of a field ofMovegeSite. - Lower biomass limit is only applied after
ST2.
Fixed
- Window sizes in multicriterial thermal definition were incorrect.
- Calculation of
fAgeDRwas incorrect. - Biomass is correctly updated after cuts.
-
dBMcan become negative, as it should. -
fWnow uses correct threshold value of 3.8 instead of 3.81. - Correction of AEv calculation.
- NULL value for simulations without cut_DOYs still produces a header in the output file.
- Bug where error message was not printed correctly in case of missing parameters.
- Biomass (BM, BMxx) was unaligned with biomass change (dBM, dBMxx).
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
dBMare 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.Rscript.S3 dispatch for plot method of
ModvegeSiteobjects ->plot(mvs)is now possible ifmvsis aModvegeSiteinstance.ParameterDatainput checking: throws error on duplicate input parameter name.Debug utility conveniences
browseandbrowse_end.ModvegeSite$plot_XXXfunctions for more insights into model behaviour, with XXX inwater,limitations,growthandplot_varfor generic variable plotting.
Changed
Input data CSV files are now actual CSV files, instead of “semicolon-separated value” files.
ParameterDatanow assumes default values for most parameters.check_parametersnow only throws an error if any of the really
required parameters are missing.Number of days per year is now inferred from weather data instead of hardcoded to 365, allowing simulations to be run for years with incomplete data.
Crop coefficient (
parameters$crop_coefficient) and senescence capping are now model parameters instead of being hardcoded.
