To reproduce full color plots and images used in various exercises in the book, please obtain these original scripts and adjust where needed. Avoid copying the code from the PDF file of the book. Note that the R code might not run on your machine, which could be due to various reasons. Most importantly, the examples in this book refer to the MS Windows operating systems mainly. There can be quite some difference between MS Windows, Linux and Mac OS X, although the same functionality should be available on both MS Windows and Linux machines. SAGA GIS is not available for Mac OS X, hence you will need to use a PC with a dual boot system to follow these exercises.
