Create a Factor Variable by Cutting an Age Variable

Description

Dividing the range of an age variable x into intervals is a frequent task. The commonly used function cut has unfavourable default values for this. CutAge() is a convenient wrapper for cutting age variables in groups of e.g. 10 years with more suitable defaults.

Usage

CutAge(x, from = 0, to = 90, by = 10, right = FALSE, ordered_result = TRUE, ...)

Arguments

x	continuous variable.
from, to	the starting and (maximal) end values of the sequence.
by	number: increment of the sequence. Default is 10, alternatives could be 5 or 20.
right	logical, indicating if the intervals should be closed on the right (and open on the left) or vice versa. Default is FALSE - unlike in cut!
ordered_result	logical: should the result be an ordered factor? Default is TRUE - unlike in cut!
...	the dots are passed on to the underlying function cut(). Use these for e.g. change the labels.

Value

A factor is returned, unless labels = FALSE which results in an integer vector of level codes.

Values which fall outside the range of breaks are coded as NA, as are NaN and NA values.
