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,
