In sybil: Efficient Constrained Based Modelling

Description

Change column (variable) objective coefficients in the optimization problem.

Usage

## S4 method for signature 'optObj_clpAPI'
changeObjCoefs(lp, j, obj_coef)

## S4 method for signature 'optObj_cplexAPI'
changeObjCoefs(lp, j, obj_coef)

## S4 method for signature 'optObj_glpkAPI'
changeObjCoefs(lp, j, obj_coef)

## S4 method for signature 'optObj_lpSolveAPI'
changeObjCoefs(lp, j, obj_coef)

Arguments

lp	An object extending class optObj.
j	A numeric vector containing the column indices of the variables to change.
obj_coef	A numeric vector of the same length as j containing the objective coefficients of the variables to change.
