ROI_plugin_solution: Extract solution from the solver.

In ROI: R Optimization Infrastructure

Description

Generic getter functions used by the function solution. These functions can be used to write a solver specific getter function.

Usage

ROI_plugin_solution_prim(x, force = FALSE)

## S3 method for class 'OP_solution'
ROI_plugin_solution_prim(x, force = FALSE)

## S3 method for class 'OP_solution_set'
ROI_plugin_solution_prim(x, force = FALSE)

ROI_plugin_solution_dual(x)

ROI_plugin_solution_aux(x)

ROI_plugin_solution_psd(x)

ROI_plugin_solution_msg(x)

ROI_plugin_solution_status_code(x)

ROI_plugin_solution_status(x)

ROI_plugin_solution_objval(x, force = FALSE)

Arguments

x	an R object inheriting from solution or solutions.
force	a logical to control the return value in the case that the status code is equal to 1 (i.e. something went wrong). By default force is FALSE and a solution is only provided if the status code is equal to 0 (i.e. success). If force is TRUE ROI ignores the status code and also returns solutions where the solver signaled an issue.

Value

the corresponding solution/s.
