If you previously have used caret for a uniform modeling interface, the tidymodels package parsnip is its more up-to-date child. Enter tidymodels, a meta-package for modeling and analysis that shares the underlying design philosophy, grammar, and data structures of the tidyverse. Much of data science involves modeling, but each modeling package seems to invent its own interface and arguments. Simplify your model explorations with tidymodels. Both approaches can be integrated with R Markdown to create polished interactive dashboards using the flexdashboard package. You can learn how to add browser-based interactivity to your graphics with just a few lines of code at If your interactive needs demand help from R code that needs to run on a server, learn how to write Shiny applications at, or follow along as Wickham ( 2020) writes the new Mastering Shiny book.

The third edition is in-progress and can be viewed for free online, with the source files on GitHub. Paper and Kindle versions are available on Amazon for the second edition of the book.
