Hi,

This has many different answers. You can :
- use ProcessBuilder to build an R process child from the java process 
(or System.exec)

- use jri to embed R within the same java process. For this you need to 
install rJava and follow the examples in the jri directory. See 
http://www.rforge.net/JRI/ http://www.rforge.net/rJava/

- run RServe and connect to it via the java client : 
http://www.rforge.net/Rserve/

rJava and Rserve share the same mailing list : 
http://mailman.rz.uni-augsburg.de/mailman/listinfo/stats-rosuda-devel 
where I would suggest you to repost (after you have browsed these options)
