convert an integer to fips

The Federal Information Processing Standards (fips) codes are available as 5-digit, 0-padded numbers. To standardize these codes for joins across datasets, one may need to convert raw integers (non-0-padded) to 5-digit numeric strings. This function does that.

Usage

integer_to_fips(v)

integer_to_state_fips(v)

Arguments

v

integer vector of state-level fips to be converted

Value

character vector with each member a 0-padded representation of the original integer value.

Functions

• integer_to_state_fips():
