 ## Acknowlegements
 
 We acknowledge Robin Lovelace, Jakub Nowosad, and Jannes Muenchow---authors of [Geocomputation with R](https://r.geocompx.org/) (Robin and Jakub also author the present book), a book on the same topic for a different programming language (R). The structure, topics, and most of the theoretical discussions were adapted from that earlier publication.
