I'm not sure what you mean. Could you please be more specific?
You were trying to eval an expression that you constructed in Java. I
was suggesting that before you eval it, you print it.
If I print the string, I get: /boxM(boxMVariable[, -5],
boxMVariable[, 5])/
Right, that's what I was suggesting you do. Now you've fixed the
syntax
error, that looks okay.
If I'm reading these messages in the right order, your latest error is
Error in |[.data.frame|(boxMVariable, , -5) : undefined columns
selected
The expression there is a funny way of printing boxMVariable[,-5]. So
now you need to figure out why it thinks you've selected undefined
columns. This is a little perplexing, because you're asking for all
columns except column 5, and that works whether or not you have a
column
5.
So I'd guess there's something weird about boxMVariable. You should ask
R to print it, and to print str(boxMVariable), to make sure it's a
regular dataframe containing 4 numeric columns and one factor or
character column.

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.

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.

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,
