# S4 method for optObj_lpSolveAPI
backupProb(lp)
An object of the same class as given in argument lp (extending class
'>optObj).
signature(lp = "optObj_clpAPI")method to use with package optObj_clpAPI.
signature(lp = "optObj_cplexAPI")method to use with package optObj_cplexAPI. The new problem object will be in the same CPLEX environment like the original one.
signature(lp = "optObj_glpkAPI")method to use with package optObj_glpkAPI. Building a new problem object will reset all parameters to their default. After backing up, set all parameters which are not at their default values again.
signature(lp = "optObj_lpSolveAPI")method to use with package optObj_lpSolveAPI.
Superclass '>optObj and constructor function
