Hi
I was trying to estimate simultaneous equation system in R using systemfit.
I used the following commands
>library(systemfit)
> data(Kmenta)
> attach(Kmenta)
>eqDemand<-consump~price+income
> eqSupply<-consump~price+farmprice+trend
> fitsur<-systemfit("SUR",list(demand=eqDemand, supply=eqSupply))
and got the following error messege
Error in systemfit("SUR", list(demand = eqDemand, supply = eqSupply)) :
argument 'formula' must be an object of class 'formula' or a list of objects
of class 'formula'
Can anyone tell me how to overcome this problem?
regards
Anwesha
