The website serves as a platform for the Introduction to Data Science book, originally derived from HarvardX Data Science Series class notes. Updates are announced on Twitter, and the book’s Quarto files are available on GitHub. The graphical theme is maintained throughout the book using the dslabs package. Acknowledgments go out to contributors and developers of R and R packages, with special mentions for Jenna Landy, David Robinson, Amy Gill, and many others. The book has undergone several refinements over the years, inspired by various online classes and contributors via GitHub pull requests. Additional resources are available for a hardcopy version and a free PDF.
