Generate Cross-Validation Folds

Convenience wrapper around crossval_samples for use inside fit_roi methods. Separates fold generation from the iteration engine so that models can generate folds directly.

Usage

generate_folds(cv_spec, data, y)

Arguments

cv_spec

A cross-validation specification object (e.g., blocked_cross_validation).

data

A data.frame or tibble of training data.

y

Response variable (factor, numeric vector, or matrix).

Value

A tibble with columns ytrain, ytest, train, test, and .id.
