Subject: [Rd] How to do a "Box's M" Test with
Message-ID: <0gfmi0-qChmzBTHTekAMzkG0n4sXaP6kQm70JHcOMVcd1GxX22gb8OYHXJKEUpti2UR4gwCyyITdGXJouMEPfYhKyhb0fQn6rElCOPY8Vvg=@protonmail.com>

Trying to get past a frustrating error to do a "simple" Box'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 string with everything commented, but nothing I've tried works.

Can anyone please suggest something to try?

Thanks in advance.

- M
