Extract CNP components

Description

The extract_() family of functions provides tools to extract the different pieces of information encoded in the CNP. These functions return a character vector:

• extract_sex() extracts the sex ("M" or "F") based on the S component of the CNP.

• extract_birth_year() extracts the year of birth, inferred from the S (which also encodes the century of birth, alongside the sex ) and AA (encoding the final 2 digits of the birth year) components of the CNP.

• extract_birth_month() extracts the month of birth based on the "LL" component.

• extract_county() gets the county of issue (based on the JJ component).

• extract_status() extracts the residence status (based on the S component)

This function returns a date vector:

• extract_dob() gets the date of birth (based on the S, AA, LL, and ZZ components).

Usage

extract_sex(x)

extract_birth_year(x)

extract_birth_month(x)

extract_dob(x)

extract_county(x)

extract_status(x)

Arguments

x	a cnp vector.

Value

• extract_sex(): a character vector containing the parsed sex: M or F.

• extract_birth_year(): a character vector containing the birth year.

• extract_birth_month(): a character vector containing the birth month.

• extract_county(): a character vector containing the county of issue.

• extract_status(): a character vector containing the residence status ("native" or "resident").

• extract_dob(): a vector of containing the date of birth.

)
