Acknowledgements

Writing R for Plant Disease Epidemiology (R4PDE) has benefited from the support and contributions of several people and organizations.

I thank Helen Pennington for granting permission to use her painting of coffee leaf rust on the book cover. Her work provides an appropriate visual representation of one of the classic subjects in plant disease epidemiology.

I am grateful to Prof. Laurence V. Madden for sharing data from The Study of Plant Disease Epidemics. These datasets contributed substantially to the analytical examples presented in the book.

I also thank the contributing chapter authors for sharing their expertise. Prof. Ivan A. Lizarazo contributed the chapter on remote sensing for disease detection and quantification. Prof. Nik Cunniffe contributed the chapter on compartmental models in plant disease epidemiology.

Finally, I acknowledge the open-source community for contributions that improved R4PDE, including code fixes, suggestions, pull requests, and other forms of feedback.
