Incanter
Clojure-based, R-like statistical computing and graphics environment
...It integrates core numerical libraries like Parallel Colt and JFreeChart to deliver data manipulation, modeling, statistical tests, and charting in a REPL-friendly environment. Start by visiting the Incanter website for an overview, check out the documentation page for a listing of HOW-TOs and examples, and then download either an Incanter executable or a pre-built version of the latest build of Incanter, which includes all the necessary dependencies, and unpack the file (if you would like to build it from source, read Building Incanter). You also might need to install libgfortran3 library, which is required for jblas, which is powering matrix operations (see jblas wiki for more details).
