[Rd] Problem with R.2.6.1 and JRI - All worked file wih R2.5.1

2008-01-31 Thread Vladmir Makarov 
Hello Members,
I have posted this message at R-HELP listserv, so my apology for
double posting, but members of R_HELP seem not to know/care about the
problem.

I wonder if someone also having a problem with JRI using new R 2.6.1.
To illustrate the problem, there is a simple Java driver problem
below. The program runs just fine on the other computer with R 2.5.1,
but does not run with R 2.6.1. It gives me no error messages either.
Needles to say, I have jri.dll at the classpath. Also, I have
downloaded the rJava package from R program (packages  install
packages  rJava), so version must be correct.

Any suggestions are highly appreciated,
Thanks,
Vlad



import org.rosuda.JRI.Rengine;

public class Driver {

public static void main(String[] args){
try {
String[] arg = {};
Rengine re = new Rengine(arg, false, null);
if (!Rengine.versionCheck()) {
Rengine.getVersion();
System.err.println(** Version mismatch);
System.exit(1);
}
if (!re.waitForR()) {
System.out.println(** Cannot load R);
System.exit(1);
}
double d = re.eval(3+5).asDouble();
System.out.print(D =  + d);
} catch (RuntimeException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

}

Vladimir,

your example works without problems in R 2.6.1:

C:\Program Files\R\R-2.6.1\library\rJava\jrijavac -cp JRI.jar  
Driver.java
C:\Program Files\R\R-2.6.1\library\rJava\jriset PATH=C:\Program Files 
\R\R-2.6.1\bin;%PATH%
C:\Program Files\R\R-2.6.1\library\rJava\jrijava -cp JRI.jar;. Driver
D = 8.0

I suspect that you have some setting mismatch left over from your  
previous R version.
Note that you may want to add System.exit(0) or terminate R, otherwise  
your application will be waiting for R to exit.

Cheers,
Simon
