compare_means(
  dataset,
  var1,

  conf_lev = 0.95,
  comb = "",
  adjust = "none",
  test = "t",
  data_filter = "",
  envir = parent.frame()
)

Value

A list of all variables defined in the function as an object of class compare_means

Arguments

alternative

conf_lev

Span of the confidence interval

comb

Combinations to evaluate

adjust

Adjustment for multiple comparisons ("none" or "bonf" for Bonferroni)

test

data_filter

Expression entered in, e.g., Data > View to filter the dataset in Radiant. The expression should be a string (e.g., "price > 10000")

envir
