In ck37/ck37r: Chris Kennedy's R Toolkit

Convert factors to indicator variables.

Based on code by Taylor Terry from 2013.

Usage

factors_to_indicators(
  data,
  predictors = colnames(data),
  max_levels = 200L,
  verbose = FALSE,
  to_lower = FALSE,
  data.table = FALSE
)

Arguments

data	.
predictors	.
max_levels	If a factor contains more than this many levels, issue a warning and don't convert it to indicators.
