I am a grad student and am working on a project where i need to integrate java and R. I have a front end in java and i need to call R functions and be able to dispaly the plots and graphs produced by R on my java front end. I came across some tools like SJava and rserve...but am not sure which best suits my application. Your suggestion will be really helpful.
The only valuable choice to integrate java and R is rserve. With RSjava, data don't persist between 2 two commands, so you can't set a variable in R from java in one instruction and re-use this data in the next instruction. Rserve is an client/server library, client is pure java (you can easily deploy it on *nix and Windows) and each connection has its own object space in R (only under *nix). Laurent.
You might also want to look at JGR (a Java GUI for R) to see how they have done things: http://stats.math.uni-augsburg.de/JGR/ HTH, Marc Schwartz
