PhenoFlex_fixedDynModelwrapper

Description

PhenoFlex wrapper function for the 'phenologyFitter' function using the GDH heat accumulation model and parameters of the dynamical model fixed. The default values for the dynamic model parameters are from the excel file with unknown origin.

Usage

PhenoFlex_fixedDynModelwrapper(
  x,
  par,
  A0 = 139500,
  A1 = 2.567e+18,
  E0 = 4153.5,
  E1 = 12888.8,
  slope = 1.6,
  Tf = 4
)

Arguments

x

data.frame with at least columns 'Temp' and 'JDay'

par

numeric vector of length 11 with the 'PhenoFlex' fit parameters in the following order: 1. yc, 2. zc, 3. s1, 4. Tu, 5. E0, 6. E1, 7, A0, 8. A1, 9. Tf, 10. Tc, 11. Tb and 12. slope. For details see PhenoFlex

A0

numeric. Parameter A_0 of the dynamic model

A1

numeric. Parameter A_1 of the dynamic model

E0

numeric. Parameter E_0 of the dynamic model

E1

numeric. Parameter E_1 of the dynamic model

slope

numeric. Slope parameter for sigmoidal function

Tf

numeric. Transition temperature for the sigmoidal function

Value

A single numeric value with the JDay prediction for the temperaturs in 'x$Temp' and the PhenoFlex parameters in 'par'.
