The steps should be listed in a way that it prepares the system environment to be able to test the code examples in the book.
The following software is required:
- R base
- MS Office
- Apache Java (JDK)
Although all the code should run on the R command line, I suggest you run the code in the book from R Studio instead of the R command line, as it is an IDE and is easy to use. Also, a few chapters specifically require the use of R Studio only.
