[acs-r] Error message in acs 2.0

[Ganz, Carl]

Hello Jonah,

I have had similar problems when dealing with geographies with many elements. I am guessing that you generated your geo.set by passing a vector of desired census tracts rather than doing something like,

geo.set(state=”IL”, county=”Cook”, tract=”*”)

As a result, your geo.set list has 591 geo objects. From my experience, any geo.set list with more than 550 elements will generate the error you mentioned. I have no idea whether this is a design decision, a bug, or some other issue.

When I had this problem I divided my geo.set into two geo.sets, each with less than 550 elements, fetched results for the two geographies, and then combined the output. Perhaps there is a more elegant workaround.

Kind Regards,

Subject: [acs-r] Error message in acs 2.0

Hi everyone,

I’m new to this listserv, and pretty new to R. I’ve used the acs package once before, on a fairly small set of geographies, and it was great! Now I’m trying it on a larger set, and it’s having some trouble. For reference, I’m using R version 3.2.5, and R Studio version 0.98.1103.

My geo.set has 591 elements (census tracts). I used check=T to make sure they were all good, and they are.

But when I try to use acs.fetch to download data, I’m getting the following error:

Error in if (url.test["statusMessage"] != "OK") { :
  missing value where TRUE/FALSE needed

Here’s my code:

#select race by Hispanic Origin data from ACS for selected geographies
race <- acs.fetch(endyear=2014, span=5, geography = mygeo, table.number="B03002", dataset = "acs")

Can anyone help me figure out what’s happening, and why?

Thanks!
Jonah
