Machine learning with R
Many of the algorithms needed for machine learning with R are not included as part of the base installation. Instead, the algorithms needed for machine learning are available via a large community of experts who have shared their work freely. These must be installed on top of base R manually. Thanks to R's status as free open source software, there is no additional charge for this functionality.
A collection of R functions that can be shared among users is called a package. Free packages exist for each of the machine learning algorithms covered in this book. In fact, this book only covers a small portion of all of R's machine learning packages.
If you are interested in the breadth of R packages, you can view a list at Comprehensive ...
