A number of people have contacted me to tell me that the downloadable source for Machine Learning for Dummies isn’t appearing on the Dummies site as described in the book. I’ve contacted the publisher about the issue and the downloadable source is now available at http://www.dummies.com/extras/machinelearning. Please look on the Downloads tab, which you can also find at http://www.dummies.com/DummiesTitle/productCd-1119245516,descCd-DOWNLOAD.html and navigate to Click to Download to receive the approximately 485 KB source code file.
When you get the file, open the archive on your hard drive and then follow the directions in the book to create the source code repository for each language. The repository instructions appear on Page 60 for the R programming language and on Page 99 for Python. I apologize for any problems that the initial lack of source code may have caused. If you experience any problems whatsoever in using the source code, please feel free to contact me at John@JohnMuellerBooks.com. Luca and I want to be certain that you have a great learning experience, which means being able to download and use the book’s source code because using hand typed code often leads to problems.
