tidymodels is a "meta-package" for modeling and statistical analysis that share the underlying design philosophy, grammar, and data structures of the tidyverse.

It includes a core set of packages that are loaded on startup:

  • broom takes the messy output of built-in functions in R, such as lm, nls, or t.test, and turns them into tidy data frames.

  • dplyr contains a grammar for data manipulation.

  • ggplot2 implements a grammar of graphics.

  • infer is a modern approach to statistical inference.

  • purrr is a functional programming toolkit.

  • recipes is a general data preprocessor with a modern interface. It can create model matrices that incorporate feature engineering, imputation, and other help tools.

  • rsample has infrastructure for resampling data so that models can be assessed and empirically validated.

  • tibble has a modern re-imagining of the data frame.

  • yardstick contains tools for evaluating models (e.g. accuracy, RMSE, etc.)

There are a few modeling packages that are also installed along with tidymodels (but are not attached on startup):

  • tidypredict translates some model prediction equations to SQL for high-performance computing.

  • tidyposterior can be used to compare models using resampling and Bayesian analysis.

  • tidytext contains tidy tools for quantitative text analysis, including basic text summarization, sentiment analysis, and text modeling.

To install:

require(devtools)
devtools::install_github("tidymodels/tidymodels")

When loading the package, the versions and conflicts are listed:
