tadaa_levene: Levene's Test for Homoskedasticity

In tadaatoolbox: Helpers for Data Analysis and Presentation Focused on Undergrad Psychology

Description

A thin wrapper around car::leveneTest with some formatting done.

Usage

tadaa_levene(
  data,
  formula,
  center = "median",
  print = c("df", "console", "html", "markdown")
)

Arguments

data	Data for the test
formula	Formula specifiyng groups, passed to leveneTest.
center	Method to use, either median (default for robustness) or mean.
print	Print method, default df: A regular data.frame. Otherwise passed to pixiedust::sprinkle_print_method for fancyness.

Value

A data.frame by default, otherwise dust object, depending on print.

Note

The case of center = "median" is technically called Brown–Forsythe test, so if that's selected the header for non-df returns will reflect that.
