Hello,

I am writing a Java frontend for a selfwritten R program using JRI.

Because I am working with my own S4 classes almost all of my R functions return 
a S4 object.

In the Java Program I now need to run a R function and its result should be 
assigned to a new R variable afterwards.


I tried REngine.eval(), but the returned REXP was always null.
I tried also the rni methods:

long result = 
re.rniParse("readInDataAndPreprocess(removemarked,removeflagged,substract_background)",1);
        System.out.println("Result:" + result);
        long r=re.rniEval(result, 0);
         System.out.println("Result = "+r+", building REXP");
         REXP x=new REXP(re, r);
        re.assign("resultReading", x);

but the variable resultReading was not available in R afterwards.


Has anyone of you an idea what I could do?


Thanks in advance!

Best,
Anni
