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"): method to use with package optObj_glpkAPI. Set lpdir to GLP_MAX for maximization or GLP_MIN for minimization.
signature(lp = "optObj_glpkAPI", lpdir = "numeric"): method to use with package optObj_glpkAPI. Set lpdir to -1 for maximization or 1 for minimization.
signature(lp = "optObj_lpSolveAPI", lpdir = "character"): method to use with package optObj_lpSolveAPI. Set lpdir to "max" for maximization or "min" for minimization.
signature(lp = "optObj_lpSolveAPI", lpdir = "numeric"): method to use with package optObj_lpSolveAPI. Set lpdir to -1 for maximization or 1 for minimization.
