SJava Help
...ork just fine in R but I am having trouble getting R to
work in Java. I have created a test class that looks like this:
import org.omegahat.R.Java.*;
public class Test {
public static void main(String[] args) {
ROmegahatInterpreter interp = new
ROmegahatInterpreter(ROmegahatInterpreter.fixArgs(args), flase);
}
}
The class compiles fine but when I run it I get the following output:

RVersion: R_VERSION=1.6.1
