How about describe? ds? and what happens if you save the dataset? Are
there two variables with the same name that end up in the saved file?
Does the number of variables increase after compress? or a variable
got renamed incorrectly? does the problem occur only to variable year?
or other variables in the dataset? How is 'year' special? (e.g. this
is the only variable that got compressed, or the last variable, or the
first variable, etc).

I don't get any r(110)'s if I use year in most any way except in graph box's over(). I can drop year and then I only have one left. I'm not positive but I believe this started when I used compress. I also suspect compress because I had several duplicated variables and at least one of them had two different storage types (int and byte) and I know that the byte version occurred only because of a compress.
