addRowsToProb-methods: Add New Rows (Constraints) to an Optimization Problem

Description

Add new rows (constraints) to an optimization problem.

Usage

# S4 method for optObj_clpAPI
addRowsToProb(lp, i, type, lb, ub, cind, nzval, rnames = NULL)
# S4 method for optObj_cplexAPI
addRowsToProb(lp, i, type, lb, ub, cind, nzval, rnames = NULL)
# S4 method for optObj_glpkAPI
addRowsToProb(lp, i, type, lb, ub, cind, nzval, rnames = NULL)
# S4 method for 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.
