Modeling data with functional programming in R

Modeling data with functional programming in R by Brain Lee Rowe.

From the post:

As some of you know, I’ve been writing a book (to be published by CRC Press/Chapman & Hall and released in late 2014) for the past year and a half. It’s one of those books that spans multiple disciplines so is both unique and also niche. In essence it’s a manifesto of sorts on using functional programming for mathematical modeling and analysis, which is based on my R package lambda.r. It spans the lambda calculus, traditional mathematical analysis, and set theory to 1) develop a mathematical model for the R language, and 2) show how to use this formalism to prove the equivalence of programs to their underlying model. I try to keep the book focused on applications, so I discuss financial trading systems, some NLP/document classification, and also web analytics.

The book started off as a more practical affair, but one thing that I’ve learned through this process is how to push ideas to the limit. So now it delves into quite a bit of theory, which makes it a more compelling read. In some ways it reminds me of ice climbing, where you’re scaling a waterfall and really pushing yourself in ways you didn’t think possible. Three chapters into the process, and it’s been that same combination of exhilarating challenge that results in conflicting thoughts racing through your head: “Holy crap — what am I doing?!” versus “This is so fun — wheeeee!” versus “I can’t believe I did it!”

Brain says some of the images, proofs and examples need work but that should not diminish your reading of the draft.

Do take the time to return comments while you are reading the draft.
