PhenoFlex_fixedDynModelwrapper function

PhenoFlex_fixedDynModelwrapper

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.

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 $A0$ of the dynamic model
• A1: numeric. Parameter $A1$ of the dynamic model
• E0: numeric. Parameter $E0$ of the dynamic model
• E1: numeric. Parameter $E1$ of the dynamic model
• slope: numeric. Slope parameter for sigmoidal function
• Tf: numeric. Transition temperature for the sigmoidal function

Returns

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