High-Performance R

High-Performance R: Profiling, Parallelism, and C++ Extensions with Rcpp

Core Promise:
High-Performance R shows you how to transform sluggish analyses into lightning-fast workflows. By mastering profiling tools, parallel computing, and C++ extensions via Rcpp, you'll pinpoint bottlenecks and deliver production-grade performance-without abandoning the R ecosystem you love.

Key Learnings & Benefits:

• Learn to profile R code with profvis and flamegraphs, turning execution data into clear optimization targets.

• Apply microbenchmarking and automated tests to measure improvements objectively.

• Harness all your CPU cores using parallel, foreach, and future, then scale to clusters with minimal changes.

• Integrate C++ extensions seamlessly: use Rcpp to rewrite critical loops, employ RcppParallel and RcppThread for thread-safe speedups, and maintain responsiveness to user interrupts.

• Package and deploy high-speed R services: containerize with Docker, set up continuous integration pipelines, and expose APIs via plumber or FastAPI for real-world applications.

Each chapter combines a concise concept overview, ready-to-run code snippets, and step-by-step explanations-so you can copy, paste, and run immediately. Whether you're an analyst racing deadlines or a package maintainer aiming for peak efficiency, this book equips you with battle-tested techniques straight from the author's toolkit.
