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.
