...g R warning messages in Java Code using Rserve. It is easier to trap R Error messages by using catching RSrvException. I came to know one way of fetching R Warning messages, i.e. using "withCallingHandlers", below is my Java Program, which uses withCallingHandlers of R : import org.rosuda.JRclient.*; ---------------------------RWarning.java----------------------- class RWarning { public static void main(String args[]) { try { String hostName = null; hostName = args[0]; Rconnection c = new Rconnection(hostName); c.voidEval("lastWarning <- NU...

Hey guys, I got a java gui app which loads up data into a table. How can i use R to perform statistical functions on the data in the table? P.S My question is not particularly geared towards Java coding, but more towards allowing R functionality within Java.

Hello, I am using Rserve to create a dedicated computational back-engine. I generate and pass an array of data to a java application on a separate server. I was wondering if the same is possible for an image. I believe that Rserve supports passing certain R objects and JRclient can cast these objects into their Java counterparts. If I generate a barplot in R (remotely), can I pass the graph image back to the Java application for display? Currently, I am reduced to saving the graph as a .pdf locally, passing the .pdf's filepath to the Java application and allowing the...

I understand FLEX and JAVA communicate seamlessly...
