The tidymodels framework is a collection of R packages for modeling and machine learning using tidyverse principles.

The tidymodels framework is a "meta-package" for modeling and statistical analysis that shares the underlying design philosophy, grammar, and data structures of the . It includes a core set of packages that are loaded on startup, and extra packages that are installed along with tidymodels but not attached on startup. The tidymodels framework provides tooling for modeling tasks including supervised machine learning (predictive modeling), unsupervised machine learning, time series analysis, text analysis, and more.

Tidymodels: Creating an rsplit object from training and testing data

I’m trying to make the jump from Scikit-Learn to Tidymodels and most of the time it has been relatively painless thanks to the tutorials from Julia Silge and Andrew Couch. However, now I’m stuck. Normally I would use initial_split(df, strata = x) to…
