set.constr.type: Set Constraint Type

Description

Set constraint types in an lpSolve linear program model object.

Usage

set.constr.type(lprec, types, constraints = 1:m)

Arguments

lprec

an lpSolve linear program model object.

types

either a numeric vector or a character vector containing elements from the set {1 = "<=", 2=">=" 3="=" ,="" }<="" code=""> specifying the types of constraints.

constraints

a numeric vector of unique values from the set {1, ..., m} (where m is the number of constraints in lprec) specifying which constraints to set.

Value

• a logical vector indicating whether the constraint types were successfully set is invisibly returned.
