nls picewise FvCB model
Greetings R users, maybe there is someone who can help me with this problem:
I'm trying to fit this discontinous model :
GE<-data.frame( Ci<-c(81,87,91,111,159,173,295,453,629,984),
A<-c(-0.9,1.2,3.5,8.3,13.1,14.4,22.9,27.3,29.6,32.6) )
rhs <- function(Ci, Vcmax, J, Rd) {
? ?R <-0.008314472
? ?Tleaf <-25
? ?Kc <-exp(38.05-79.43/(R*(Tleaf+273.15)))
? ?Ko
