Dear all,

I'm trying to use R-functions from Java. I want to use the Package Rserve.
Everthing is installed and I can run my Java-testprogramm.

...
Rconnection r = new Rconnection();
double[] d = r.eval("rnorm(10)").asDoubleArray();
...

But now I get always arrays with ten "0.0", which is not correct

I suppose, that is is a problem from R, because at the fist time (last week)
I started RServe I got an icon in my taskbar which was something about a R
server. But I never got it since then...
I tried to reinstall R, but it didn't help.

Where is teh problem and what can I do?

Thanks a lot, Max

I solved the problem. With a big C in RConnection and asDoubles() it works...

try{
RConnection r = new RConnection(); 
double[] d = r.eval("rnorm(10)").asDoubles();
} catch(Exception e){}
