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

[Ezra Haber Glenn]

All that said, if you *were* using span = 5 and endyear = 2016 and
still ran into problems with tract-level fetching, it could be this:

1) updating the package to 2.1.3 (cures lookup problems)

2) when running geo.make with tracts, do it like this:

> mygeo <- geo.make(state=26,county=081,tract=c("001500","001600","001900","002600"))

The quotation marks keep the leading zeroes from being dropped for
tract numbers; this didn't matter in the past, but the API seems to be
enforcing the six-digit rule for tracts starting in 2016.

Let me know if that helps.
