getOptPathBestIndex: Get index of the best element from optimization path.

Description

Get index of the best element from optimization path.

Usage

getOptPathBestIndex(op, y.name = op$y.names[1],
    dob = op$env$dob, eol = op$env$eol, ties = "last")

Arguments

op

[OptPath] Optimization path.

y.name

[character(1)] Name of target value to decide which element is best. Default is y.names[1].

dob

[integer] Possible dates of birth to select best element from. Defaults to all.

eol

[integer] Possible end of life to select best element from. Defaults to all.

ties

[character(1)] How should ties be broken when more than one optimal element is found? all: return all indices, first: return first optimal element in path, last: return last optimal e

Value

• [integer] Index or indices into path. See ties.

Examples

ps <- makeParamSet(makeNumericParam("x"))
op <- makeOptPathDF(par.set=ps, y.names="y", minimize=TRUE)
addOptPathEl(op, x=list(x=1), y=5)
addOptPathEl(op, x=list(x=2), y=3)
addOptPathEl(op, x=list(x=3), y=9)
addOptPathEl(op, x=list(x=4), y=3)
as.data.frame(op)
getOptPathBestIndex(op)
getOptPathBestIndex(op, ties="first")
