stacks: Initialize a Stack

In stacks: Tidy Model Stacking

Initialize a Stack

Description

The stacks() function initializes a data_stack object. Principally, data_stacks are tibbles, where the first column gives the true outcome in the assessment set, and the remaining columns give the predictions from each candidate ensemble member. (When the outcome is numeric, there’s only one column per candidate member. For classification, there are as many columns per candidate member as there are levels in the outcome variable minus 1.) They also bring along a few extra attributes to keep track of model definitions, resamples, and training data.

See ?stacks_description for more discussion of the package, generally, and the basics vignette for a detailed walk-through of functionality.
