Calculate ages from CPR numbers.
age(cpr, date = Sys.Date(), unit = "year")age(cpr, date = Sys.Date(), unit = "year")
cpr |
Character vector of CPR numbers with or without hyphens. |
date |
Character or date vector of dates used in computation of ages. Dates provided as characters must follow the ISO standard, 'yyyy-mm-dd'. |
unit |
Character indicating the unit representing ages. Possible values are: 'year', 'month', 'week', 'day'. |
Numeric vector of ages. By default ages are computed in years. Note that year and month units are calculated by approximaion, 1 year = 365.25 days, 1 month = 30.44 days.
age(c('1508631111', '1310762222'))age(c('1508631111', '1310762222'))
Calculate dates of birth from CPR numbers.
dob(cpr)dob(cpr)
cpr |
Character vector of CPR numbers with or without hyphens. |
Vector of dates of birth.
dob(c('1508631111', '1310762222'))dob(c('1508631111', '1310762222'))
Calculate genders from CPR numbers.
gender(cpr)gender(cpr)
cpr |
Character vector of CPR numbers with or without hyphens. |
Integer vector of genders: 0 = female, 1 = male.
gender(c('1508631111', '1310762222'))gender(c('1508631111', '1310762222'))
Check if CPR numbers conform to modulo 11 check. Note, modulo 11 check was deprecated in 2007.
mod11(cpr)mod11(cpr)
cpr |
Character vector of CPR numbers with or without hyphens. |
Logical vector of check results, NA if CPR number includes characters (temporary CPR number).
mod11(c('1508631111', '1310762222', '2110625629'))mod11(c('1508631111', '1310762222', '2110625629'))
Make "anonymous" random numbers from CPR numbers.
scramble(cpr)scramble(cpr)
cpr |
Character vector of CPR numbers with or without hyphens. |
Integer vector. Each integer represents one unique CPR number.
scramble(c('1508631111', '1310762222', '1508631111'))scramble(c('1508631111', '1310762222', '1508631111'))

test_cprtest_cpr
A data frame with 30 rows and 3 columns.
