Mathematica 9 introduced some key features for interfacing Mathematica to other systems. HTTP operations are supported with a range of functions for interacting with URLs and web sites, allowing synchronous and asynchronous interactions. Extensions to Mathematica streams allow them to be backed by data sources such as documents residing on web sites. A new toolkit for linking to the R statistical system enables users to integrate their R work with Mathematica.

R Link »

InstallR — launch the R runtime and connect it to the Wolfram System session

UninstallR — uninstall the R runtime

REvaluate — evaluate a string of R code

RSet — assign the value to a variable in R workspace
