Hi All,

OK, in the "back to the drawing board" department, I found what looks like a much better solution to using R in Java. Renjin.

Looking at the docs and then trying a quick example, didn't quite work.

Of course I'm missing something.

Although I'm telling the engine to require ("biotools") just like I would in R itself, when I get to the line of code that does the actual call

engine.eval("boxMResult <- boxM(inputIris [,-5], inputIris[,5])");

Then, I get:

Exception in thread "main" org.renjin.eval.EvalException: could not find function 'boxM'

Am I using Renjin as intended? Biotools is installed in R and works fine from RStudio.

I didn't see any examples in the docs (please excuse if I missed) that bring in any libraries.

Entire Java source below.

Thanks in advance,

----

public class RCallerExample{
public static void main(String[] args)
{
// create a script engine manager:RenjinScriptEngineFactory factory = new RenjinScriptEngineFactory();
// create a Renjin engine:ScriptEngine engine = factory.getScriptEngine();

try{
engine.eval("require(biotools)");
