reconstruct_formulas

lifecycle::badge("maturing")
In the (cross-)validation results from functions like
 <code>cross_validate()</code>,
 the model formulas have been split into the columns
 <code>Dependent</code>, <code>Fixed</code> and <code>Random</code>.
 Quickly reconstruct the model formulas from these columns.

Cross-validate one or multiple regression and classification models
and get relevant evaluation metrics in a tidy format. Validate the
best model on a test set and compare it to a baseline evaluation.
Alternatively, evaluate predictions from an external model. Currently
supports regression and classification (binary and multiclass).

 or <code>validate()</code>. (tbl)
Must contain at least the columns <code>"Dependent"</code> and <code>"Fixed"</code>. For random effects,
 the <code>"Random"</code> column should be included.</dd>
