They are kept as an attribute if use.value.labels=TRUE, whether or not a factor is created. I had thought they were always kept as an attribute even if use.value.labels=FALSE (as happens with read.dta), but this turns out not to be the case. This is easily fixed, and I will do so.

I have thought about a class that would make sense for data with some values labelled but not all. This is related to some other data representation issues that a colleague is asking about, and we may come up with a reasonably elegant and general solution.
