I was looking for some third party jars to do some advanced analytical process like SQL window functions in Java,since our database mysql did not support it. With the help of google I found "R" though it is not java based but it can solve most of my cases. I have tried "RJava" and "Rcaller" interface to connect java.
For performance,scalability and long run which is the best library to connect R inside Java. Kindly advice.
