Aggregate Age Group Labels

Convert age group labels to a less detailed classification. The three classifications recognized by combine_age() are "single", "five", and "lt", as defined on age_labels(). The following conversions are permitted:

• "single" —> "lt"

• "single" —> "five"

• "lt" —> "five"

Usage

combine_age(x, to = c("five", "lt"))

Arguments

x

A vector of age labels

to

Type of age classification to convert to: "five" or "lt". Defaults to "five".

Value

If x is a factor, then combine_age() returns a factor; otherwise it returns a character vector.

• age_labels() to create age group labels

• reformat_age() to convert existing age group labels to a standard format

• set_age_open() to set the lower limit of the open age group

Examples

x <- c("0", "5", "3", "12")
combine_age(x)
#> [1] "0-4"   "5-9"   "0-4"   "10-14"
combine_age(x, to = "lt")
#> [1] "0"     "5-9"   "1-4"   "10-14"
