train_idx

Integer vector of training indices.

test_idx

Integer vector of test indices.

Value

A list with detailed CV leakage information.

Examples

# Using caret trainControl
if (requireNamespace("caret", quietly = TRUE)) {
  folds <- list(Fold1 = 1:10, Fold2 = 11:20, Fold3 = 21:25)
  ctrl <- caret::trainControl(method = "cv", index = folds)
  report <- cv_leakage_report(ctrl, train_idx = 1:25, test_idx = 26:32)
  print(report)
