getCat {simPop}

Categorize (semi-)continuous variables

Description

Categorize continuous or semi-continuous variables. This is a utility function that is useful for writing custom wrapper functions such as simEUSILC.

Usage

getCat(x, breaks, zeros = TRUE, right = FALSE)

Arguments

x

a numeric vector to be categorized.

breaks

a numeric vector of two or more break points.

zeros

a logical indicating whether x is semi-continuous, i.e., contains a considerable amount of zeros. See “Details” on how this affects the behavior of the function.

right

logical; if zeros is not TRUE, this indicates whether the intervals should be closed on the right (and open on the left) or vice versa.

Details

If zeros is TRUE, 0 is added to the break points and treated as its own factor level. Consequently, intervals for negative values are left-closed and right-open, whereas intervals for positive values are left-open and right-closed.

Value

A factor containing the categories.
