Import R-output into Java
Thanks, sink was exactly the function I searched.
It properly works in R, but when I try to launch it from Java, the file is
created but never written any output...
con.voidEval("test.txt"); // file is created
con.voidEval("1+1"); // nothing is written into the file
con.voidEval("sink()");
Where is my mistake?
Cheers, Max

Hello,
I want to import R-output via Rserve to Java, especially for the function
ctree from the package party.
Rserve is working properly.
Yet, I only get the predictions with the Java code
try{
RConnection c = new RConnection();
...
c.voidEval("modell <- ctree(...)");
REXP y = c.eval("nodes(modell,1)[[1]]$prediction");
...
}catch(Exception e){}
When I try to get the whole text with
REXP z = c.eval("nodes(modell,1)[[1]]");
System.out.println(z);
I get something like
org.rosuda.REngine.REXPGenericVector at 119c082+[10]named
But I want the text which is printed in R.
What can I do?
Thanks, Max
Once again:
It`s clear to get the result in R but I don`t know hoe to get the
R-output
into Java (or into a file, i.e. .txt)
