R: Get Sensitivity: Right-Hand-Side

get.sensitivity.rhs {lpSolveAPI} | R Documentation

## Get Sensitivity: Right-Hand-Side

### Description

Retrieve the sensitivity of the constraints from a successfully solved lpSolve linear program model object.

### Usage

    get.sensitivity.rhs(lprec)

### Arguments

`lprec` | an lpSolve linear program model object.

### Value

a list with components

`duals` | a numeric vector of length `m+n` (where `m` is the number of constraints in `m` and `n` is the number of decision variables in `lprec`) containing the values of the dual variables (reduced costs).
`dualsfrom` | a numeric vector of length `m+n` (where `m` is the number of constraints in `m` and `n` is the number of decision variables in `lprec`) containing the values of the lower limits on the dual variables.
`dualstill` | a numeric vector of length `m+n` (where `m` is the number of constraints in `m` and `n` is the number of decision variables in `lprec`) containing the values of the upper limits on the dual variables.

### Examples

    lps.model <- make.lp(0, 3)
    xt <- c(6,2,4)
    add.constraint(lps.model, xt, "<=", 150)
    xt <- c(1,1,6)
    add.constraint(lps.model, xt, ">=", 0)
    xt <- c(4,5,4)
    add.constraint(lps.model, xt, "=", 40)
    set.objfn(lps.model, c(-3,-4,-3))

    solve(lps.model)
    get.sensitivity.rhs(lps.model)
