[R] Problem with package SJava

[Nathan Whitehouse]

Hi,

  This main method on class Essai will fail at least
for one reason becaue you need to instantiate a
ROmegahatInterpreter.
  
  Referencing this causes the R DLLs & the SJava DLLs
to load.  
   However, it appears that they are already loaded,
judging from your output below based on the signal
11/Page fault error.

  Try adding it and seeing if it works.  Can you get
it to work under linux?

  About the java compilation issue:
  
  you need to have the following jars in your
CLASSPATH

    $SJAVA_HOME/org/omegahat/Jars/jas.jar
    $SJAVA_HOME/org/omegahat/Jars/antlr.jar
    $SJAVA_HOME/org/omegahat/Jars/Environment.jar

  This might cause the compilation issue.

  Hope that is a little help.  If you still have
problems, hopefully we can figure them out.

Hello all,
I'm trying to run SJava package (0.65 modified
downloaded from : 
http://stats.math.uni-augsburg.de/iPlots/alpha/) on
windows NT 2000 and 
R 
1.8.01. I have also downloaded the PDF Calling R from
Java and when I 
want 
to execute the following code:
import org.omegahat.R.Java.*;
import java.io.*;
public class Essai{
	public static void main (String [] args) {
		REvaluator e = new REvaluator();
		Object val = e.eval("objects()");
		if (val!= null)  {
			String[] objects = (String[]) val;
			for (int i = 0; i< objects.length; i++) {
				System.out.println("("+i+") " + objects[i]);
			}
		}
	}
}
I have in return:


An unexpected exception has been detected in native
code outside the 
VM.

I try to recompile the native interfaces and I think
that some files or 
directories are missing like:
antlr\commonAST.class
jas.classEnv

I don't know what I should do so I hope that anybody
could help me.
thanks,
Regards

Vincent
