My problem is that I still have trouble running the example code in WINDOWS. I copy your code and run it in RStudio, yet "could not find function" is klling me. is there any chance you can solve that?Linux is not available for us, not to mention oracle java. If you can build a R package, maybe more user-friendly?
Thanks~
