get.basis: Get Basis

Description

Retrieve the basis from a solved lpSolve linear program model object.

Usage

get.basis(lprec, nonbasic = FALSE)

Arguments

lprec

an lpSolve linear program model object.

nonbasic

a logical value. If TRUE, the nonbasic variables are returned as well.

Value

• an integer vector containing the indices of the basic (and nonbasic if requested) variables. If an error occurs (for instance when calling get.basis on a model that has not yet been solved) a NULL value is returned.
