effect_counts_items_grouped_items(
  data,
  cols,
  cross,
  method = "cramer",
  labels = TRUE,
  clean = TRUE,
  ...
)

Arguments

data: A tibble containing item measures and grouping variable.
cols: Tidyselect item variables (e.g. starts_with...).
cross: The columns holding groups to compare.
method: The output metrics: cramer = Cramer's V, f1 = F1-value (only for variable sets with the same labels).
labels: If TRUE (default) extracts labels from the attributes, see codebook.
clean: Prepare data by data_clean.
...: Placeholder to allow calling the method with unused parameters from effect_counts.

Value

A volker tibble.
