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'.
