rob.cases {SetMethods}

Function for identifying cases in the intersections between an inital solution and test solutions.

Description

Function for identifying cases between the various intersections between an inital solution and test solutions. The function also returns case ratio paramaters.

Usage

rob.cases(test_sol, 
           initial_sol, 
           outcome)

Arguments

test_sol

The different alternative solutions created with minimize() and placed in a list using list().

initial_sol

The initial solution created with minimize().

outcome

A character string containing the name of the outcome.
