Usage

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

Arguments

iraceResults

(list()|character(1)) iraceResults 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

drop.metadata

Remove metadata, such the configuration ID and the ID of the parent, from the returned configurations. See removeConfigurationsMetaData.

Value

A data frame containing the elite configurations required.
