demand <- q ~ p + d
supply <- q ~ p + f + a
labels <- list( "demand", "supply" )
system <- list( demand, supply )

## perform OLS on each of the equations in the system
fitols <- systemfit( "OLS", system, labels )

## print the residuals of the first equation
residuals( fitols$eq[[1]] )

## print the residuals of the second equation
