Well, if you posted to the correct list (stats-rosuda-devel) you would have
increased your chance of getting help considerably.

That "problem" is a bug in the Java program -- the constructor it is
using does NOT initialize R but is used to hook into an already running R
(please consult the docs: http://rforge.net/org/docs/). That program should
read:

            Rengine re=new Rengine(args, false, null);
            re.assign("x", "Peter");

Also note that it is discouraged to use the low-level API. It is preferable for
new projects to use the high-level org.rosuda.REngine API instead:

	REngine eng =
REngine.engineForClass("org.rosuda.REngine.JRI.JRIEngine");
	eng.assign("x", "Peter")

It is far more flexible and more safe that he direct API. Also it allows you to
switch to several back-ends.

Cheers,
Simon
