Chris:

Thanks for your email, and for using the acs.R package.

When you say, "I'm working with a sample of people...," I'm assuming
you mean a sample of blocks (or block groups), correct?  If so, then I
think this should be possible, if we parse the complete fips codes to
send the correct parts to state=, county=, tract=, etc.  Can you send
me a few sample codes you'd want to us (maybe 5-10, ideally also
telling me in plain English what geographies they represent), and I
can recommend a couple lines of code to create the correct geo.set
from them?
