The datasets we use here for data mining will all be CSV format. As we will learn in Section 4.5 Rattle supports loading data from a number of sources. In addition to that though, R supports loading data from many more sources and formats, and once loaded into R, these datasets are also then available to Rattle.

The sample datasets used in this book are included as part of the rattle package and can be directly access in R by first loading the rattle package into the R library, and then using the data function to make the dataset available:
