[R] Missing values?

Simple question: I have imported a table from SPSS via read.spss,
but I have not figured out how to tell R that values 8,9 are
considered NA.

After reading help, I thought that something like


would go, but apparently it doesn't (mean gives the same value
without regards to na.rm).

Could anybody help me, please?

See, when the GOVERNMENT spends money, it creates jobs; whereas
when the money is left in the hands of TAXPAYERS, God only knows
what they do with it. Bake it into pies, probably. Anything to
avoid creating jobs.
