An options manager for configuring chickpea model parameters. This object provides methods to get and set chickpea related parameters.

chickpea

Available Options

phenology.thermal_time.x

Cardinal temperatures for thermal time calculation. Default: c(2, 30, 35)

phenology.thermal_time.y

Effective thermal time at corresponding cardinal temperatures. Default: c(0, 28, 0)

phenology.vernalisation_time.x

Cardinal temperatures for vernalisation time calculation. Default: c(0, 2, 8, 15)

phenology.vernalisation_time.y

Effective vernalisation time at corresponding cardinal temperatures. Default: c(0, 1, 0.5, 0.0)

Methods

get(key)

Retrieve the value of an option by its key (e.g., "phenology.thermal_time.x")

set(key, value)

Set the value of an option by its key

reset()

Reset all options to their default values

Examples

# Get default thermal time cardinal temperatures
chickpea$get("phenology.thermal_time.x")
#> [1]  0 30 40

# Get default vernalisation time parameters
chickpea$get("phenology.vernalisation_time.x")
#> [1]  0.0  4.7  8.0 14.0
chickpea$get("phenology.vernalisation_time.y")
#> [1] 0.0 1.0 0.5 0.0

# Set custom values
chickpea$set("phenology.thermal_time.x" = c(0, 25, 40))
chickpea$set("phenology.thermal_time.y" = c(0, 25, 0))

# Reset to defaults
chickpea$reset()
