Applies combiners: functions that collapse across a list of
similarly structured results, to a list of such lists.
combine_results(results, combiners = NULL, smart_combiners = TRUE)A list of combined results.
A list of lists, corresponding to each result,
with the inner lists corresponding to results from each fold.
A list with the same names as results, containing
combiner function names or functions for each result.
A logical indicating whether combiners should
be guessed from the data type of the results if they are missing.
In theory you should never call this function directly, because it is called automatically by cross_validate. The defaults, combiners guessed based on data type, should work in most cases.
