Consider how `step_select()` handles outcomes and predictors

## The problem If model is fit for `workflows::workflow()` and recipe steps include `step_select`, then `predict.workflow` fails. However, the same recipe works fine without using workflows package. ## Reproducible example...

## Feature When testing multiple model types (e.g., in an ensemble workflow), one could create a baseline recipe that works for most of the models. Then if one model has...

All the steps contain a number of arguments, many of which are standard arguments that the user won't/shouldn't touch. Should there be some highlighting/muting in the documentation to guide the...

PLS loadings from step_pls() differ from plsda() ones

3

## The problem I tried to compare results of a PLS dimension reduction with `recipes::step_pls()` and `mixOmics::plsda()` (at the begining, to recreate a importance plot like `mixOmics::plotLoadings()` in a tidy...

Similarly to how it was done in https://github.com/tidymodels/recipes/pull/927 for `step_normalize()`. # Reprex ``` r library(recipes) dat % step_range(x) %>% prep() %>% bake(new_data = NULL) #> # A tibble: 100 ×...
