Option list used in the make_data() function

Description

The options list handed to make_data(). It specifies the process model options. An example is provided by standard_options.

Arguments

optim

String specifying the data calculated by the user defined Model function, e.g. one of c("DEoptim", "LaplacesDemon").

ve

String specifying the version of the process model. Must be one of c("std", "fqr", "red", "oak").

steps

Integer numeric vector specifying the timesteps to output. The process model will run max(steps) iterations and the output will contain length(steps) output times.

initial_mass_par

Boolean specifying if the initial biomass used in the process model should be estimated as a parameter.

initial_mass

The initial biomass to use for the process model, when initial_mass_par is set to FALSE.

species

A vector of names of species.

photo

A vector specifying the photosynthesis system used by the species. Must be either c("c3", "c4") for each species.

swc_online

Boolean specifying if soil water content should be calculated online as part of the process model (TRUE) or if it is given as a forcing parameter. Currently not supported.

lc

Boolean turning light competition simulation in the process model on/off. Currently not supported.

fire

Boolean turning fire in the process model on/off. Currently not supported.

pe

Boolean turning process error simulation on/off.

pe_scale

The process error scaling factor.
