[Rd] Cannot Compute Box's M (Three Days Trying...)

It can't be this hard, right? I really need a shove in the right direction
here. Been spinning wheels for three days. Cannot get past the errors.

I'm doing something wrong, obviously, since I can easily compute the
Box's M right there in RStudio

But I don't see what is wrong below with the coding equivalent.

The entire code snippet is below. The code fails below on the call to the boxM
statistic call.

PLEASE HELP!!!

Thanks in advance,

[Rd] Cannot Compute Box's M (Three Days Trying...)

Does it work if you supply the closing parenthesis on the call to boxM?
The parser says the input is incomplete and a missing closing parenthesis
would cause that error..

// create a string command with that variable name.String boxVariable
"boxM(boxMVariable [,-5], boxMVariable[,5]";

// try to execute the command...
// FAILS with org.rosuda.REngine.Rserve.RserveException: eval failed,
request status: R parser: input incomplete>>>> FAILS !
>>>>  REXP
theBoxMResult = rConnection.eval(boxVariable);    <<<< FAILS
<<<<<

[Rd] Cannot Compute Box's M (Three Days Trying...)

Just print the string you are asking to R to evaluate.  It doesn't make 
any sense as an R expression.  Fix that, and things will work.

[Rd] Cannot Compute Box's M (Three Days Trying...)

Hi Bill,

Thanks for catching that. However, the problem remains.

If I use R debugging code with the rResponseObject below, I get a maybe better
error, but it still doesn't make sense.

This is the actual error R is throwing:

Error in `[.data.frame`(boxMVariable, , -5) : undefined columns selected

Does this error make sense?

Please reply. :)

Thanks in advance.

---------------

<R Debugging code, one line substituted from earlier posting>

REXP rResponseObject = rConnection.parseAndEval("try(eval(" +
boxVariable+ "),silent=TRUE)");
if (rResponseObject.inherits("try-error"))
{
System.out.println("R Serve Eval Exception : " +
rResponseObject.asString());
}

The parser says the input is incomplete and a missing closing parenthesis would
cause that error..

[Rd] Cannot Compute Box's M (Three Days Trying...)

I'm not sure what you mean. Could you please be more specific?

If I print the string, I get:  boxM(boxMVariable[, -5], boxMVariable[, 5])

From this code:
.
.
.
// assign the data to a variable.rConnection.assign("boxMVariable",
myDf);

// create a string command with that variable name.String boxVariable =
"boxM(boxMVariable[, -5], boxMVariable[, 5])";

System.out.println(boxVariable);  // print the string? Not sure what is meant.

Sorry if I didn't understand your suggestion.

Look forward to hearing back from you.

Thanks,
