# Introduction

This book aims to be a complement to the 2nd edition [An Introduction to Statistical Learning](https://www.statlearning.com/) book with translations of the labs into using the [tidymodels](https://www.tidymodels.org/) set of packages.

The labs will be mirrored quite closely to stay true to the original material.

## Edition Differences {-}

All listed changes will be relative to the 1st edition.

- [Naive Bayes](04-classification.qmd#naive-bayes) has been added to chapter 4 on [Classification](04-classification.qmd)
- [Poisson Regression](04-classification.qmd#poisson-regression) has been added to chapter 4 on [Classification](04-classification.qmd)
- "Application to Caravan Insurance Data" section is no longer treated as its own section and is now part of the [K-Nearest Neighbors](04-classification.qmd#k-nearest-neighbors) section
- [Bayesian Additive Regression Trees](08-tree-based-methods.qmd#bayesian-additive-regression-trees) has been added to chapter 8 on [Tree-Based Methods](08-tree-based-methods.qmd)
- chapter on [Unsupervised Learning](12-unsupervised-learning.qmd) has been renumbered to chapter 12 instead of 10
- [Matrix Completion](12-unsupervised-learning.qmd#matrix-completion) has been added to chapter 12 on [Unsupervised Learning](12-unsupervised-learning.qmd)

## Colophon {-}

This book was written in [RStudio](https://posit.co/products/open-source/rstudio/) using [**Quarto**](https://quarto.org/). The [website](https://emilhvitfeldt.github.io/ISLR-tidymodels-labs/index.html) is hosted via [GitHub Pages](https://pages.github.com/), and the complete source is available on [GitHub](https://github.com/EmilHvitfeldt/ISLR-tidymodels-labs).

This version of the book was built with `r R.version.string` and Quarto version `r system("quarto --version", intern = TRUE)` and the following packages:

```{r}
#| echo: false
#| results: asis
deps <- desc::desc_get_deps()
pkgs <- sort(deps$package[deps$type == "Imports"])
pkgs <- sessioninfo::package_info(pkgs, dependencies = FALSE)
df <- tibble::tibble(
  package = pkgs$package,
  version = pkgs$ondiskversion,
  source = gsub("@", "\\\\@", pkgs$source)
)
knitr::kable(df, format = "markdown")
```
