Examples

# Wide data - default
data_wide <- data.frame(A = c(4, 2, 5, 3, 6, 2, 5),
                        B = c(5, 2, 1, 2, 1, 3, 2))

compare_means_between_groups(data_wide, var1 = A, var2 = B)

# Long data
data_long <- data_wide |> tibble::rowid_to_column("id") |>
  tidyr::pivot_longer(cols = -id, names_to = "group", values_to = "variable")

compare_means_between_groups(data_long, variable = variable,
                             grouping_variable = group, groups = c("A", "B"), input = "long")
