EXCEPTION_ACCESS_VIOLATION when trying to use RJava

Question

So I'm trying to make use of R from Java through JRI. I'm using the RJava plugin for Eclipse and the two test files which come with rJava are working fine (rtest and rtest2). But when trying to run this simple code fragment, I get an EXCEPTION_ACCESS_VIOLATION:

public static void main(String... args) {
    Rengine re = new Rengine();

    if (!re.waitForR()) {
        System.out.println("Unable to load R");
        return;
    } else
        System.out.println("Connected to R");

    re.eval("x=c(1:10)");
    double d = re.eval("mean(x)").asDouble();
    System.out.println(d);
}

The output I'm getting:

    Connected to R

A fatal error has been detected by the Java Runtime Environment:

I'm seeing this in the log, does it have to do something with it? (wrong use of the eval function? I just copied an example though...)

If anybody could help, I'm at a loss and would appreciate it greatly :)

Answer 1

Instanitiate rengine like below, i have just made 10 as default size.

String args1[] = new String[10];
Rengine rengine = new Rengine(args, false, null);

You have to set the environment variable R_HOMEin your JVM environment. Set it in your environment variable won't work, JVM is NOT ware of that. Just figured it out by myself.
