Arguments

lp

An object extending class '>optObj.

lpdir

A single character string, numeric or integer value. Can be set to "max" or -1 for maximization, or "min" or 1 for minimization. For packages cplexAPI and glpkAPI it is also possible to use the corresponding constant given by the package.

Methods

signature(lp = "optObj_clpAPI", lpdir = "character")

method to use with package optObj_clpAPI. Set lpdir to "max" for maximization or "min" for minimization.

signature(lp = "optObj_clpAPI", lpdir = "numeric")

method to use with package optObj_clpAPI. Set lpdir to -1 for maximization or 1 for minimization.

signature(lp = "optObj_cplexAPI", lpdir = "character")

method to use with package optObj_cplexAPI. Set lpdir to "max" for maximization or "min" for minimization.

signature(lp = "optObj_cplexAPI", lpdir = "integer")

method to use with package optObj_cplexAPI. Set lpdir to CPX_MAX for maximization or CPX_MIN for minimization.

signature(lp = "optObj_cplexAPI", lpdir = "numeric")

method to use with package optObj_cplexAPI. Set lpdir to -1 for maximization or 1 for minimization.

signature(lp = "optObj_glpkAPI", lpdir = "character")

method to use with package optObj_glpkAPI. Set lpdir to "max" for maximization or "min" for minimization.

signature(lp = "optObj_glpkAPI", lpdir = "integer")
