addRowsToProb-methods

Add New Rows (Constraints) to an Optimization Problem

Description

Add new rows (constraints) to an optimization problem.

Usage

## S4 method for signature 'optObj_clpAPI'
addRowsToProb(lp, i, type, lb, ub, cind, nzval, rnames = NULL)

## S4 method for signature 'optObj_cplexAPI'
addRowsToProb(lp, i, type, lb, ub, cind, nzval, rnames = NULL)

## S4 method for signature 'optObj_glpkAPI'
addRowsToProb(lp, i, type, lb, ub, cind, nzval, rnames = NULL)

## S4 method for signature 'optObj_lpSolveAPI'
addRowsToProb(lp, i, type, lb, ub, cind, nzval, rnames = NULL)

Arguments

`lp`	An object extending class `optObj`.
`i`	A numeric vector containing the new row indices.
`type`	A character vector giving the constraint type: `"F"`: free constraint (optObj_glpkAPI only), `"L"`: `>=` (lower bound), `"U"`: `<=` (upper bound) or `"D"`: `lb <= r <= ub` (double bound) or `"E"`: `=` (equality). If `type[k]` is not `F`, `"L"`, `"U"`, `"D"` or `"E"`, the value of `type[k]` will be set to `"E"`.
`lb`	A numeric vector containing the lower bound of the new constraints.
`ub`	A numeric vector containing the upper bound of the new constraints.
`cind`	A list containing the column indices of the new non-zero elements.
`nzval`	A list containing the new non-zero elements.
`rnames`	A character vector containing names for the new rows/constraints. Default: `NULL`.

Methods

signature(lp = "optObj_clpAPI"): method to use with package optObj_clpAPI. Parameter rnames is currently unused.
signature(lp = "optObj_cplexAPI"): method to use with package optObj_cplexAPI.
signature(lp = "optObj_glpkAPI"): method to use with package optObj_glpkAPI.
signature(lp = "optObj_lpSolveAPI"): method to use with package optObj_lpSolveAPI.

Note

Arguments i, type, lb, cind, nzval and rnames (if not NULL) must have the same length.
