Overview

tidymodels is a “meta-package” for modeling and statistical analysis that shares 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.

  • dials has tools to create and manage values of tuning parameters.

  • dplyr contains a grammar for data manipulation.

  • ggplot2 implements a grammar of graphics.

  • infer is a modern approach to statistical inference.

  • parsnip is a tidy, unified interface to creating models.

  • 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.

  • tune contains the functions to optimize model hyper-parameters.

  • workflows has methods to combine pre-processing steps and models into a single object.

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

A list of all tidymodels functions across different CRAN packages can be found at https://www.tidymodels.org/find/.

You can install the released version of tidymodels from CRAN with:

install.packages("tidymodels")

Install the development version from GitHub with:

# install.packages("pak")
pak::pak("tidymodels/tidymodels")

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

cloudstart's Issues

SSL Certificate for Urchins data

Hello! Very minor because I can always download the data manually in a browser but I think the SSL certificate for the urchins data may have expired, I can't use read_csv to download the data from the tidymodels site as shown in the "Build a Model" page from getting started. Reprex below.

library(tidymodels)  # for the parsnip package, along with the rest of tidymodels
#> Registered S3 method overwritten by 'tune':
#>   method                   from   
#>   required_pkgs.model_spec parsnip

# Helper packages
library(readr)       # for importing data
#> 
#> Attaching package: 'readr'
#> The following object is masked from 'package:yardstick':

#>     spec
#> The following object is masked from 'package:scales':

  # Data were assembled for a tutorial 
  # at https://www.flutterbys.com.au/stats/tut/tut7.5a.html
  read_csv("https://tidymodels.org/start/models/urchins.csv") %>% 
  # Change the names to be a little more verbose
  setNames(c("food_regime", "initial_volume", "width")) %>% 
  # Factors are very helpful for modeling, so we convert one column
  mutate(food_regime = factor(food_regime, levels = c("Initial", "Low", "High")))
#> Error in open.connection(structure(4L, class = c("curl", "connection"), conn_id = <pointer: 0x3cf>), : SSL certificate problem: certificate has expired

Move `master` branch to `main`

The master branch of this repository will soon be renamed to main, as part of a coordinated change across several GitHub organizations (including, but not limited to: tidyverse, r-lib, tidymodels, and sol-eng). We anticipate this will happen by the end of September 2021.

That will be preceded by a release of the usethis package, which will gain some functionality around detecting and adapting to a renamed default branch. There will also be a blog post at the time of this master --> main change.

The purpose of this issue is to:

  • Help us firm up the list of targetted repositories
  • Make sure all maintainers are aware of what's coming
  • Give us an issue to close when the job is done
  • Give us a place to put advice for collaborators re: how to adapt
