Returns the configurations by the iteration in which they were executed.

Usage

getConfigurationByIteration(iraceResults, iterations, 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.
iterations: integer()
The iteration number or a vector of iteration numbers from where the configurations should be obtained. Negative values start counting from the last iteration.
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.
