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])");
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 an R variable, and paste the name of that variable into your expression, or to construct a language object containing the dataframe object, but I don't know how to do those things.

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 Sent from [ProtonMail](https://protonmail.com), Swiss-based encrypted email.
