The projects I walk you through in this book are vehicles for sharpening your R skill set. These projects depend on R packages specialized for the topics I cover. In this chapter, I tell you about some packages that can serve as the foundation for additional projects, and for further honing your R skills.
These packages address subject areas I cover in this book, and one area that I don’t.
The goal of the
caret package is to make it easy for you to work with machine learning. Consistent with R formula notation, its simple syntax connects with a huge array of machine learning methods. Additionally, the package offers a number of data sets to try them out on. If I were writing a book about the gamut of machine learning, I'd include this package. (In fact, it might cover only this package.)
As its name implies, the
neuralnet package is all about neural networks. It goes beyond
nnet (the package that ...
