Why R?

This book uses R.

Many of its ideas could also be implemented in Python or other languages. The most important decision here is not that one language must defeat all others. It is the decision to work with an open programming language rather than relying exclusively on proprietary, point-and-click statistical software.

R is free and open source. It has a large community and a broad ecosystem for data preparation, visualisation, statistics, modelling, reporting, and teaching. The same environment can take us from raw data to a graph, a model, an interactive exercise, or an entire book.

This eBook is itself produced with R, R Markdown, and Bookdown.
