Accent R

Accent, also known as A Programming Language for Data Analysis and Statistical Modeling, is a programming language for solving statistical problems. It shares the same syntax and semantics with R at the user level but allows users to write their own packages in a language that can be compiled into machine code. It was developed by Jay Emerson, Nick Horton, and Ron Zemel at Yale University to get better performance from R's interpreted code structure on large datasets or complex algorithms. Accent programs are created with a mixture of C++-like object-oriented syntax and R-like data manipulation capabilities. The code is then compiled using an LLVM-based compiler before being executed within the R environment using JIT (Just-In-Time) compilation techniques provided by the compiler package in CRAN (The Comprehensive R Archive Network).
