<div>I’m sure there’s a simple answer to this. My attempts so far have crashed and burned.</div>
<div><br>
</div>
<div>I’m trying to create ACS estimates of population from Table B01003 for 3-digit ZCTAs nationwide. I need these as a basis for measuring per capita rates of some other data that is available only at the 3-digit ZCTA level. </div>
<div><br>
</div>
<div>I have a data frame of 33,000 5-digit ZCTAs with total estimated population, the margin of error and the 3-digit ZCTA (a substring of the 5-digit ZCTA). I want to create a new data frame consisting of 3-digit ZCTAs with their estimated populations and
margin of error.</div>
<div><br>
</div>
<div>I tried to do this using variations on the geo.make() function:</div>
<div><br>
</div>
<div>
<div>> census2 = geo.make(substring(census1$ZCTA5,1,3))</div>
<div>Error: evaluation nested too deeply: infinite recursion / options(expressions=)?</div>
</div>
<div><br>
</div>
<div>And</div>
<div><br>
</div>
<div>
<div>> census2 = geo.make(census1, combine=TRUE, combine.term='ZCTA3')</div>
<div>Error in (function (us, region, division, state, county, county.subdivision, : </div>
<div> (list) object cannot be coerced to type 'double'</div>
</div>
<div><br>
</div>
<div>Any ideas?</div>
<div><br>
</div>
<div>Thanks.</div>
