Find all blocks within each of the FIPS codes provided

Allows EJAM to analyze and compare Counties, for example

Usage

getblocksnearby_from_fips(fips, inshiny = FALSE, need_blockwt = TRUE)

Arguments

fips

vector of FIPS codes identifying blockgroups, tracts, counties, or states. This is useful if – instead of gettings stats on and comparing circular buffers or polygons – one will be getting stats on one or more tracts, or analyzing and comparing blockgroups in a county, or comparing whole counties to each other, within a State.

inshiny

used by shiny app server code to handle errors via validate() instead of stop()

need_blockwt

set to FALSE to speed it up if you do not need blockwt

Value

same as for getblocksnearby but one row per FIPS, and the distance column is irrelevant

Examples

  x <- getblocksnearby_from_fips(fips_counties_from_state_abbrev("DE"))
  counties_ej <- doaggregate(x)
  #cannot use mapfast(counties_ej$results_bysite) since no lat lon.  mapfastej_counties() should work...
  y =  ejamit(fips=fips_counties_from_statename("Delaware"))
  
  # x=getblocksnearby_from_fips("482011000011") # one blockgroup only
  # y=doaggregate(x)
