addVar: Method for adding variables to a linear program
In TSSP: Two-Stage Stochastic Programs

Additional arguments to the addVar-method pertinent to the defined S4-classes in this package are detailed below.

1 2	## S4 method for signature 'CLPD' addVar(object, add2obj, newAcol, varNames = NULL, newBound = NULL, rhs = NULL)

`object`	`CLPD`: an object of class `"CLPD"`, ordinarily returned by a call to `LPD()`.
`add2obj`	`vector`: The coefficients to be added to the objective function.
`newAcol`	`matrix`: The columns to be added to the constraint matrix `A`.
`varNames`	`NULL` or `vector`: The character vector of variable names; if left `NULL` and `add2obj` has no names, then generic names will be created.
`newBound`	`NULL` or `list`: If left `NULL`, the default bounds in Rglpk will be used, otherwise a `list`-object as expected in `Rglpk_solve_LP()`.
`rhs`	`NULL` or `vector`: The changed values for the rhs-constraints, if applicable.
