Return the elite configurations of the final iteration.

Usage

getFinalElites(iraceResults, n = 0L, drop.metadata = FALSE)

Arguments

iraceResults: list()|character(1)
Object created by irace and typically saved in the log file irace.Rdata. If a character string is given, then it is interpreted as the path to the log file from which the iraceResults object will be loaded.
n: Number of elite configurations to return, if n is larger than the number of configurations, then only the existing ones are returned. The default (n=0) returns all of them.
drop.metadata: logical(1)
Remove metadata, such as the configuration ID and the ID of the parent, from the returned configurations. See removeConfigurationsMetaData().

Value

A data frame containing the elite configurations required.
