When working with the rsample package, a simple recipe must be prepared using the prep function first. When using recipes with rsample it is helpful to have a function that can prepare a recipe across a series of split objects that are produced in this package. prepper is a wrapper function around prep that can be used to do this. See the vignette on "Recipes and rsample" for an example.

prepper(split_obj, recipe, ...)



An rplit object


An untrained recipe object.


Arguments to pass to prep such as verbose or retain.


prepper() sets the underlying prep() argument fresh to TRUE.
