Update method for the 'EffFlexi' Model class. This is a method to update estimates both for the flexible form model and the random walk model (see details in EffFlexi class object) when new data or new observations of responses are available and added in.

Description

Update method for the 'EffFlexi' Model class. This is a method to update estimates both for the flexible form model and the random walk model (see details in EffFlexi class object) when new data or new observations of responses are available and added in.

Usage

## S4 method for signature 'EffFlexi'
update(object, data, ...)

Arguments

object	is the model which follow EffFlexi class object
data	all currently available data and responses of DataDual class object
...	unused

Value

the new EffFlexi class object

Examples

##Update the 'EffFlexi' model with new data
## first define the data and the model
emptydata<-DataDual(doseGrid=seq(25,300,25))
data<-emptydata

Effmodel<- EffFlexi(Eff=c(1.223, 2.513),Effdose=c(25,300),
                    sigma2=c(a=0.1,b=0.1),sigma2betaW=c(a=20,b=50),smooth="RW2",data=data)


##Then we have some new observations data
data<-DataDual(x=c(25,50,50,75,100,100,225,300),y=c(0,0,0,0,1,1,1,1),
               w=c(0.31,0.42,0.59,0.45,0.6,0.7,0.6,0.52),
               doseGrid=seq(25,300,25))

##update the model to get new estimates
newEffModel <- update(object=Effmodel,data=data)
