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
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.

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 in path, “random”: return random optimal element in path. Default is “last”.

Value

integer Index or indices into path. See ties.
