Java-R integration?

Question

I have a Java app which needs to perform partial least squares regression. It would appear there are no Java implementations of PLSR out there. Weka might have had something

Answer 1

I had similar need a while back and tested a few of the interfaces to R. The one I found to be the best for my needs (windows, c#) was Rserve which I believe is written in Java. My only gripe with it is that it wasn't 64-bit. I used a simple client written in c# and it worked very well. I'm sure the Java client is a lot better.
