Computational science: R


Have you heard R before? I am sure you know it well as a character in English, but for a very important statistical programming language, you may don’t know it very much. R is a free software programming language and software environment for statistical computing and graphics. [1]

Do you still remember my open source blog? If you have read it, you must know R is becoming the most popular R is becoming the most popular worldwide applied statistical language. It is widely used among statisticians and data miners for developing statistical software and data analysis. R could not only help academics to solve  most challenging problems in fields ranging from computational biology to quantitative finance, but also to train their students in these fields. The most amazing part of R is it enable advanced user to manipulate R objects directly with C, C++, or Java code.

We have a word in statistics: R could do almost everything for you. R provides a wide variety of statistical and graphical techniques, including linear and nonlinear modeling, classical statistical tests, time-series analysis, classification, clustering, and others. [2] R has similar syntax as language C, and it is also a functional programming language. It has strong compatibility with APL and Lisp. In particular, it allows computing on the language. This makes it possible to input expression.
