See: http://www.scienceops.com/Rlink2.asp http://library.wolfram.com/infocenter/Conferences/6510/ Those provide hints on calling R from Mathematica using a commercial application (Windows Vista only apparently). It would seem, logically, that the commercial world (SAS, SPSS, etc.) has deemed it more important to provide R functionality from within their applications, than vice versa. If Mathematica can be run in a batch mode using a CLI interface, it may be possible to call Mathematica from within R using the system() function. However, parsing the results of the Mathematica operation in R will be up to you. Similarly, if Mathematica has the ability to call external batch files, you could run R code in that fashion, again, having to deal with parsing the results in Mathematica. In so far as moving data back and forth, you can review the R Data Import/Export manual: http://cran.r-project.org/doc/manuals/R-data.html to identify common formats (eg. CSV files) that can be used by both applications. I don't use Mathematica, so am unfamiliar with their, presumably proprietary, formats.
