[R] Forecasting with macroeconomic structural equations models?

[Ronaldo Carpio]

Hello,

Is there a package or sample code that shows how to do ex ante 
forecasts with a macroeconomic structural equations model?  I looked
at the "sem" package, which lets you estimate e.g. Klein's model, but
I'm not sure how to make simulations using the full set of equations,
including the identities.


Thank you,
