[acs-r] Error in downloading 2016 census data?

[Ezra Haber Glenn]

Ugh.  Here's the deal, I think:

It seems that the census folks have *once again* changed the format of
the ACS variable lookup code XML files, which is messing up the
package -- sorry about that.  (Each year has a different set of
variable code tables, so this problem only affects the latest one,
2016.)

Basically, at this point, the package needs to make all sorts of
little corrections for each different endyear/span combination.  I'll
try to troubleshoot and get it to work. 

In the meanwhile, here's a clever trick you can use to trick the
package to use the variable numbers from a previous year (which is
safe, unless the variable numbers change, which is pretty rare):

# save a lookup from a year that works
a=acs.lookup(table.number = "B02001", endyear=2015, span=5)

# use this in your new fetch:
acs.fetch(geography = all_counties, variable=a, endyear=2016, span=5)


Ta-da!

Let me know if that sort of thing works, or if you have more questions.
