Preprocess Last Names and Geographic Identifiers
Description
These functions are called automatically by [bisg()] but may be useful, especially when geographic variables are included in a [birdie()] model. 'proc_zip()' and 'proc_state()' preprocess their corresponding geographic identifiers. States are partially matched to state names and abbreviations and are returned as FIPS codes. ZIP codes are crosswalked to Census ZCTAs. Missing identifiers are replaced with '"<none>"'. 'proc_name()' processes last names in accordance with Census processing rules (<https://www2.census.gov/topics/genealogy/2010surnames/surnames.pdf>). Names are converted to Latin characters, capitalized, stripped of prefixes and suffixes, and otherwise standardized.
Usage
proc_zip(x)
proc_state(x)
proc_name(x, to_latin = TRUE)
Arguments
x |
A character vector of names or geographic identifiers to process |
to_latin |
If 'TRUE', convert names to Latin characters only. Strongly recommended if non-Latin characters are present, since these will not match Census tables. However, the conversion is slightly time-consuming and so can be disabled with this flag. |
Value
A processed character vector
Functions
-
proc_zip(): Match ZIP codes to ZCTAs and fill in missing values. -
proc_state(): Match state names and abbreviations and fill in missing values. -
proc_name(): Process names to a Census-standardized format.
Examples
proc_name("Smith Jr.")
proc_zip("00501")
proc_state("Washington")
