Process Binary Variables in a Data Frame — margot_process_binary

This function identifies binary variables (both factors and numeric), converts them to 0/1 format, and renames them. It allows for exceptions to be specified, and ignores variables whose names already end with the specified suffix.

Usage

margot_process_binary_vars(data, exceptions = character(0), suffix = "_binary")

Arguments

data: A data frame to process.
exceptions: A character vector of column names to exclude from processing.
suffix: A string to append to renamed binary variables. Default is "_binary".

Value

A data frame with processed binary variables.

Examples

df <- data.frame(
  a = factor(c("yes", "no", "yes")),
  b = c(1, 0, 1),
  c = c("apple", "banana", "apple"),
  d = factor(c("true", "false", "true")),
  e_binary = c(0, 1, 0)
)
processed_df <- margot_process_binary_vars(df, exceptions = "c")
