Renjin?
...enjin.
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...

How to do a "Box's M" Test with
...;s M test using Java.
The Box's M test says it will work with a data.frame.
Here's the setup code:
REXP myDf = REXP.createDataFrame(new RList(
new REXP[]
{
new REXPDouble(d1),
new REXPDouble(d2),
new REXPDouble(d3),
new REXPDouble(d4),
new REXPInteger(d5)
}));
Here's the call:
REXP boxMResult = rConnection.eval( "boxM(" + myDf+ "[,-5], " + myDf + " [, 5])");
But, I keep getting syntax errors.
If this code isn't right, how do you build a data.frame R will like? No examples I can find, anywhere.
Not sure what to try next. I've tried just sending a...

I don't really know the R Java interface, but this doesn't make sense.
You are pasting an REXP object myDf into a string to evaluate. It would
make sense to assign that dataframe object to a...
