Simon Urbanek Rserve -- A Fast Way to Provide R Functionality to Applications *************************************************************** Rserve is a TCP/IP server which allows other programs to use facilities of R from various languages without the need to initialize R or link to the R library. Every connection has a separate workspace and working directory. Client-side implementations are available for popular languages such as C/C++ and Java. Rserve supports remote connection, authentication and file transfer. This paper describes the Rserve concept, compares it with other techniques and illustrates its use on several practical examples.
