Hello
I m tryng to execute the code below and I have a problem with the R-Java
connection.:
import org.omegahat.R.Java.*;
public class REvalSample {
public static void main(String [] args) {
String [] rargs = {"--slave", "--vanilla"};
System.out.println("Sample program to call R engine from
Java");
ROmegahatInterpreter interp = new
ROmegahatInterpreter(ROmegahatInterpreter.fixArgs(rargs),false);
REvaluator e = new REvaluator();
Object val = e.eval("demo()");
val = e.eval("x * 2.0");
if (val != null) {
double[] objects = (double[])val;
for (int i=0; i<objects.length; i++) {
System.err.println("("+i+") " +
objects[i]);}
}
}
}
The ERROR MESSAGES are
""Loading RInterpreter library

You keep on asking questions on this topic lacking basic information. Please consult the posting guide: 1) Do not send HTML mail. 2) Do tell us your OS and platform. 3) Do ask the maintainer about contributed packages. There are alternatives to SJava, for example Rserve and JRI at http://www.rosuda.org/software/ (and see the R FAQ). On Wed, 10 May 2006, miniar mansouri wrote:> hello, > I want to call R from java.
