One thing I notice is that after using subset() on a data frame
imported from SPSS, my variable.names attribute disappeared. I guess
what I would expect is for a subset() method always to preserve
everything but the omitted column.

iris[, nm != "Species" ]
iris[, -match("Species", nm)]

I agree with the submitter that this needs some kind of solution.
Although data.frame[,-12] works, how do I drop a named column (the
most common use case)? (I found this bug while searching for an
answer.)
