Get Sensitivity: Objective

Description

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

Usage

get.sensitivity.obj(lprec)

Arguments

lprec an lpSolve linear program model object.

Value

a list with components

objfrom a numeric vector of length n (where n is the number of decision variables in lprec) containing the values of the lower limits of the objective function.
objtill a numeric vector of length n (where n is the number of decision variables in lprec) containing the values of the upper limits of the objective function.
