getOptPathParetoFront: 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
)

Value

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

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.
