getOptPathParetoFront {ParamHelpers}R Documentation

Get indices of pareto front of optimization path.

Description

Get indices of pareto front of optimization path.

Usage

getOptPathParetoFront(op, y.names = op$y.names, dob = op$env$dob,
  eol = op$env$eol, index = FALSE)

Arguments

op

[OptPath]
Optimization path.

y.names

[character]
Names of performance measures to construct pareto front for. Default is all performance measures.

dob

[integer]
Vector of date-of-birth values to further subset the result. Only elements with a date-of-birth included in dob are selected. Default is all.

eol

[integer]
Vector of end-of-life values to further subset the result. Only elements with an end-of-life included in eol are selected. Default is all.

index

[logical(1)]
Return indices into path of front or y-matrix of nondominated points? Default is FALSE.

Value

[matrix | integer]. Either matrix (with named columns) of points of front in objective space or indices into path for front.
