makeLogical: Logical variable check

In IQSS/PSI-Library: Differentially Private Statistical Releases for Privacy Preservation

Description

Utility function to verify that a variable is dichotomous.

Usage

makeLogical(x)

Arguments

x	Vector containing two unique types of values.

Details

This function effectively allows the user to ask for any variable containing at most two unique values to treat the variable as logical. If the variable contains numeric values, the highest value is recoded 1 and the the lower value is recoded 0. If the variable is categorical and contains only two unique values, the least frequently observed is recoded 1.

Value

Logical form of x coded 0-1.

Examples

makeLogical(sample(c('cat', 'dog'), size=8, replace=TRUE))
makeLogical(sample(c(0, 1), size=8, replace=TRUE))
makeLogical(sample(c(-6.87, 3.23), size=8, replace=TRUE))
