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 element i

Value

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