abbr_to_fips: Get FIPS codes from state abbreviations

Description

Look up FIPS codes by state abbreviations (including District of Columbia and Puerto Rico); this function is based on grep(), and hence allows for regular expressions.

Usage

abbr_to_fips(
  abbr,
  ignore.case = TRUE,
  perl = FALSE,
  fixed = FALSE,
  ties_method = c("first", "all")
)

Value

A vector of FIPS codes if ties_method equals "first", and a list of FIPS codes otherwise. These FIPS codes have five digits (ending in "000").

Arguments

abbr

Vector of state abbreviations to look up.

ignore.case, perl, fixed

Arguments to pass to grep(), with the same defaults as in the latter function, except for ignore.case = TRUE. Hence, by default, regular expressions are used; to match against a fixed string (no regular expressions), set fixed = TRUE.

ties_method

If "first", then only the first match for each name is returned. If "all", then all matches for each name are returned.

abbr_to_fips("PA")
abbr_to_fips(c("PA", "PR", "DC"))

# Note that name_to_fips() works for state names too:
name_to_fips("^Pennsylvania$")
