I would like to thank Packt Publishing for this opportunity, Kajal Thapar and Utkarsha S. Kadam for their fantastic support and editing, and everyone from the R community for making life simpler and data science interesting.

Finally, I would to thank my family, especially my parents and brother for their faith in me and for whom this book will be a surprise. I would also like to thank my mentors, teachers, and friends, who have always been an inspiration. Last but not least, special thanks to my partner in crime, Dipanjan Sarkar, without whom this wouldn't have been possible.

Much gratitude goes without saying to Packt Publishing for giving me this wonderful opportunity to share my knowledge with the machine learning and R enthusiasts out there who are doing truly amazing things every day.
