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
