The function automatically combines a list of BenchmarkResult objects into a single BenchmarkResult object as long as the full crossproduct of all task-learner combinations are available.
(list of BenchmarkResult)
Note that if you want to merge several BenchmarkResult objects, you must ensure that all possible learner and task combinations will be contained in the returned object. Otherwise, the user will be notified which task-learner combinations are missing or duplicated.
When merging BenchmarkResult objects with different measures, all missing measures will automatically be recomputed.
