Gain an accelerated introduction to domain-specific languages in R, including coverage of regular expressions. This compact, in-depth book shows you how DSLs are programming languages specialized for a particular purpose, as opposed to general purpose programming languages. Along the way, you´ll learn to specify tasks you want to do in a precise way and achieve programming goals within a domain-specific context.

Domain-Specific Languages in R includes examples of DSLs including large data sets or matrix multiplication; pattern matching DSLs for application in computer vision; and DSLs for continuous time Markov chains and their applications in data science. After reading and using this book, you´ll understand how to write DSLs in R and have skills you can extrapolate to other programming languages.

What You´ll Learn

Program with domain-specific languages using R

Discover the components of DSLs

Carry out large matrix expressions and multiplications

Implement metaprogramming with DSLs

Parse and manipulate expressions

Who This Book Is For

Those with prior programming experience. R knowledge is helpful but not required.
