set.constr.type {lpSolveAPI} | R Documentation |
Set constraint types in an lpSolve linear program model object.
set.constr.type(lprec, types, constraints = 1:m)
lprec |
an lpSolve linear program model object. |
types |
either a numeric vector or a character vector containing elements from the set {1 = "<=", 2 = ">=", 3 = "="} 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. |
a logical vector indicating whether the constraint types were successfully set is invisibly returned.
