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
