Setup a Resampler (Deprecated)

Description

setup_Resampler() is deprecated. Use setup_KFold(), setup_StratSub(), setup_StratBoot(), setup_Bootstrap(), setup_LOOCV(), or setup_Custom(). Only arguments relevant to the selected type are forwarded. Omitted arguments retain the selected setup function's default resolution.

Usage

setup_Resampler(
  n_resamples = 10L,
  type = c("KFold", "StratSub", "StratBoot", "Bootstrap", "LOOCV", "Custom"),
  stratify_var = NULL,
  train_p = 0.75,
  strat_n_bins = 4L,
  target_length = NULL,
  id_strat = NULL,
  seed = NULL,
  verbosity = 1L,
  resamples = NULL
)

Arguments

n_resamples	Integer [1, Inf): Number of resamples to make.
type	Character: Resampling method; matched without regard to case.
stratify_var	Optional Character: Variable to stratify by.
train_p	Numeric (0, 1): Training set percentage.
strat_n_bins	Integer [1, Inf): Number of bins to stratify by.
target_length	Optional Integer [1, Inf): Target length for stratified bootstraps.
id_strat	Optional Character: Name of the column holding per-case grouping IDs, e.g. subject IDs when the dataset contains repeated measurements. Cases sharing an ID stay in the same resample, so a case can only be present in the training or the test set, not both. Requires that resample() be given the data frame the column lives in. train takes the column as a case identifier, so it groups the resamples by it and excludes it from the features.
seed	Optional Integer [0, Inf): Random seed.
verbosity	Integer: Console verbosity. The deprecation warning is always signaled and can be handled with suppressWarnings().
resamples	Optional List: Resamples to use, one integer vector of training-case indices per resample.

Details

id_strat names a column in the input data; per-case ID vectors are not accepted. Arguments that do not apply to the selected type are ignored.

Value

A resampler configuration of the selected type.

Examples

config <- suppressWarnings(setup_Resampler(5L, "KFold", seed = 2026L))
