This function identifies and returns a list of binary variables
in a dataframe. Binary variables are defined as having exactly two unique values
or levels. The function supports options for handling ordinal factors and
revalued data.
Usage
getBinaryVars(DataFrame, Ordinal = TRUE, Revalued = TRUE)
Arguments
- DataFrame
A dataframe to analyze for binary variables.
- Ordinal
Logical. If TRUE, ordinal factors are included in the search
for binary variables. Default is TRUE.
- Revalued
Logical. If TRUE, the function checks factors and their levels;
otherwise, it checks for variables with two unique values.
Value
A character vector containing the names of binary variables.
