Rserve is a TCP/IP server which allows other programs to use facilities of R (see www.r-project.org) from various languages without the need to initialize R or link against Rlibrary. Every connection has a separate workspace and working directory. Client-side implementations are available for popular languages such as C/C++, PHP and Java.Rserve supports remote connection, authentication and file transfer. Typical use is to integrate R backend for computation of statstical models, plots etc. in other applications.
