Returns the pairs of instance IDs and seeds used as instances in the race (and optionally the actual instances).

Usage

get_instanceID_seed_pairs(iraceResults, index, instances = 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.
index: (integer())
Indexes of the (instanceID,seed) pairs to be returned. The default returns everything.
instances: (logical(1))
Whether to add the actual instances as an additional column (only if the instances are of atomic type).

Value

data.table()
With default arguments, a data.table containing two columns "instanceID" and "seed". With instances=TRUE and if the instances are of atomic type (see is.atomic()) type, another column instance is added that contains the actual instance.
