The only software needed for this book is R itself, which is available for download for all major operating systems at http://cran.r-project.org. Some additional R packages are required, but these can be installed from within R. The instructions are provided in the relevant sections of the book.
You will also need the example datasets, which can be downloaded from the book's companion website: https://www.packtpub.com/r-graph-cookbook/book.
