Compute Age in Years

Source: R/compute_age_years.R
compute_age_years.Rd

Converts a set of age values from the specified time unit to years.

Usage 

compute_age_years(age, age_unit)

Arguments

age

The ages to convert.

A numeric vector is expected.

Default value

none

age_unit

Age unit.

Either a string containing the time unit of all ages in age or a character vector containing the time units of each age in age is expected. Note that permitted values are cases insensitive (e.g. "YEARS" is treated the same as "years" and "Years").

Permitted values

"years", "months", "weeks", "days", "hours", "minutes", "seconds", NA_character_.

Default value

none

Value

The ages contained in age converted to years.

Details

Returns a numeric vector of ages in years as doubles. Note that passing NA_character_ as a unit will result in an NA value for the outputted age. Also note, underlying computations assume an equal number of days in each year (365.25).

Examples 

compute_age_years(
  age = c(240, 360, 480),
  age_unit = "MONTHS"
)
#> [1] 20 30 40

compute_age_years(
  age = c(10, 520, 3650, 1000),
  age_unit = c("YEARS", "WEEKS", "DAYS", NA_character_)
)
#> [1] 10.000000  9.965777  9.993155        NA
