## Not run: library( linprog )
## Production activities
cvec <- c(1800, 600, 600) # gross margins
names(cvec) <- c("Milk","Bulls","Pigs")
## Constraints (quasi-fix factors)
bvec <- c(40, 90, 2500) # endowment
names(bvec) <- c("Land","Stable","Labor")
## Needs of Production activities
Amat <- rbind( c( 0.7, 0.35, 0 ),
c( 1.5, 1, 3 ),
c( 50, 12.5, 20 ) )
## Maximize the gross margin
res <- solveLP( cvec, bvec, Amat, TRUE )
## prepare and print the summary results
summary( res )
