# Preface

• This book is currently (as of April 2020) in preperation.
• This book is intended to serve as an online update to my “physical” book (Chakraborty 2017). Since its publication in 2017 the RJafroc package, on which the R code examples in the book depend, has evolved considerably, causing many of the examples to “break”. This has also given me the opportunity to improve on the book.
