Hi
I was trying to estimate simultaneous equation system in R using systemfit.
I used the following commands
>eqDemand<-consump~price+income
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

PLEASE!

You already sent this to R-help .. which makes sense ..

do *NOT* send such questions to other mailing lists, like 
'R-SIG-robust'  to which it really does *not* belong.
