newColsCPLEX: Add Empty Columns to a Specified CPLEX Problem Object

In cplexAPI: R Interface to C API of IBM ILOG CPLEX

Description

Low level interface function to the IBM ILOG CPLEX function CPXnewcols. Consult the IBM ILOG CPLEX documentation for more detailed information.

Usage

newColsCPLEX(env, lp, ncols,
             obj = NULL, lb = NULL, ub = NULL,
             xctype = NULL, cnames = NULL)

Arguments

env	An object of class "cplexPtr" as returned by openEnvCPLEX. This is basically a pointer to an IBM ILOG CPLEX environment.
lp	An object of class "cplexPtr" as returned by initProbCPLEX. This is basically a pointer to an IBM ILOG CPLEX problem object.
ncols	Number of variables to add.
obj	Objective function coefficients.
lb	Lower bounds on the new variables.
ub	Upper bounds on the new variables.
xctype	Type of the new variables.
cnames	Names of the new variables.

Details

Interface to the C function newCols which calls the CPLEX function CPXnewcols.

Value

Zero if successful, otherwise nonzero.
