ABOUT ADVANCED R
This is the website for 2nd edition of Advanced
R, a book in Chapman Halls R Series. The
book is designed primarily for R users who want
to improve their programming skills and
understanding of the language. It should also
be useful for programmers coming to R from

INTRODUCTION
R, at its heart, is a functional language. This
means that it has certain technical properties,
but more importantly that it lends itself to a
style of problem solving centred on functions.
Below Ill give a brief overview of the
technical definition of a functional language,
but in this book I will primarily focus on the
functional style of programming, because I think
it is an extremely good fit to the types of
problem you commonly encounter when doing data
analysis.

What are advanced R skills?

• This course covers advanced topics in R
  programming that are necessary for developing
  powerful, robust, and reusable data science
  tools. Topics covered include functional
  programming in R, robust error handling, object
  oriented programming, profiling and
  benchmarking, debugging, and proper design of
  functions.

things that are worth emulating in your
own code and youll develop a sense of
taste for what makes good R code.
