PhenoFlex_fixedDynModelGAUSSwrapper

Description

PhenoFlex wrapper function for the 'phenologyFitter' function using the GAUSS heat accumulation model and parameters of the dynamical model fixed.

Usage

PhenoFlex_fixedDynModelGAUSSwrapper(
  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 (in degree Kelvin) 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'.
