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,
