After correlate(), the primary corrr functions take a cor_df as their first argument, and return a cor_df or tbl (or output like a plot). md: this is a top-level page on the site rendered from a single . The name reflects the idea that tuning predictive models can be like turning a set of dials on a complex machine under duress. These steps are available here in a separate package because the step dependencies, rstanarm, lme4, and keras, are fairly heavy. nestedmodels enhances the ‘tidymodels’ set of packages by allowing the What needs to be developed for tidymodels? parsnip already contains some simple wrappers for parametric survival models but, to really be useful, there is a fair amount of infrastructure needed.

The source of the website is a collection of . I believe tidymodels packages will correctly call (from R) any special compiled code that is set up for GPU use, but we don't currently lay out which models or feature engineering steps can do that; currently this requires the user to know more about how, say, they can set up keras or xgboost for GPU use. tidymodels has 59 repositories available.
