set.rhs: Set Right-Hand-Side

Description

Set elements on the right-hand-side of an lpSolve linear program model object.

Usage

set.rhs(lprec, b, constraints = 1:m)

Arguments

lprec

an lpSolve linear program model object.

b

a numeric vector of length m (where m is the number of constraints in lprec)

constraints

a numeric vector containing unique elements from the set {1, ..., m} (where m is the number of constraints in lprec) identifying the constraints for which to set the right-hand-side value.

Value

• a logical vector indicating whether setting each right-hand-side element was successful.

Examples

lps.model <- make.lp(4, 2)
x <- c(6,2,4,9)
set.column(lps.model, 2, x)
y <- c(3,1,5)
ind <- c(1,2,4)
set.column(lps.model, 1, y, ind)

set.rhs(lps.model, c(10, 20, 40, 80))
