Set Bounds

Description

Set bounds on the decision variables in an lpSolve linear program model object.

Usage

set.bounds(lprec, lower = NULL, upper = NULL, columns = 1:n)

Arguments

`lprec`	an lpSolve linear program model object.
`lower`	a numeric vector of lower bounds to be set on the decision variables specified in `columns`. If `NULL` the lower bounds are not changed.
`upper`	a numeric vector of upper bounds to be set on the decision variables specified in `columns`. If `NULL` the upper bounds are not changed.
`columns`	a numeric vector of values from the set `{1, ..., n}` specifying the columns to have their bounds set. If `NULL` all columns are set.

Value

a NULL value is invisibly returned.
