StepChill_Wrapper R Documentation
StepChill_Wrapper
Description
Same as UniChill_Wrapper, but with a step function for chilling
Usage
StepChill_Wrapper(x, par)
Arguments
x
data.frame with at least columns 'Temp' and 'JDay'
par
numeric vector of length 7 with the parameters of the
StepChill model: 1. Tc, 2. bf, 3. cf, 4. Cstar and 5. Fstar.
Value
A single numeric value with the JDay prediction for the
