separate_age_groups: Separate Age Group Column into Min and Max Age of Range

In GerkeLab/fcds: Process Data from the Florida Cancer Data System

Description

Takes the age group stored in age_group and creates two variables, age_min and age_max with the age boundaries of the group. By default, separate_age_groups() assumes that the age group definitions are separated by a dash ("-"), possibly with whitespace on either side. The separator can be specified using the sep argument.

Usage

separate_age_groups(data, age_group = age_group, ...,
  sep = "\\s*-\\s*", into = c("age_min", "age_max"))

Arguments

data	A data frame.
age_group	Unquoted column name containing the age grouping.
...	Not used other than to require explicit naming of arguments.
sep	Separator between columns. If character, is interpreted as a regular expression. The default value is a regular expression that matches any sequence of non-alphanumeric values. If numeric, interpreted as positions to split at. Positive values start at 1 at the far-left of the string; negative value start at -1 at the far-right of the string. The length of sep should be one less than into.
into	Character vector of column names for separated age_group. If NULL, then _min and _max will be appended to the name of the age_group column. Must be two names in the order min then max.

See Also

format_age_groups() for the specification of the age group label format and to convert age boundaries into age group labels.

  id = 1:4,
  age_group = c("0 - 4", "10 - 14", "65 - 69", "85+")
