Usage

addConstraint(p, sense, rhs, coefs = NULL, name = NULL)

Arguments

p	an object of class lpmodeler
sense	sense of the constraint (<, >, <=, >=, == or !=)

p <- newProblem()

# add variables x and y
p <- addVariable(p, "C", 5, "x")
p <- addVariable(p, "C", 4, "y")

# add the constraint: x + 2y >= 5
p <- addConstraint(p, ">=", 5, c(1, 2), name = "x+2y greater or equal than 5")

# add the empty constraint: <= 10
p <- addConstraint(p, "<=", 10, name = "less or equal than 10")
