#' @param aggregator (`function()`)\cr
#' Function to aggregate over multiple iterations. The role of this function depends on
#' the value of field `"average"`:
#'
#' * `"macro"`: A numeric vector of scores (one per iteration) is passed.
#' The aggregate function defaults to [mean()] in this case.
#' * `"micro"`: The `aggregator` function is not used.
#' Instead, predictions from multiple iterations are first combined and then
#' scored in one go.
#' * `"custom"`: A [ResampleResult] is passed to the aggregate function.
