Pairwise Wilcoxon tests

Description

pairwise_wilcox_test calculates pairwise comparisons on ordinal data between all group levels with corrections for multiple testing based on coin::wilcox_test from package 'coin'.

Usage

pairwise_wilcox_test(
  dep_var,
  indep_var,
  strat_var = NA,
  adjmethod = "fdr",
  distr = "exact",
  plevel = 0.05,
  symbols = letters[-1],
  sep = ""
)

Arguments

dep_var	dependent variable, containing the data.
indep_var	independent variable, should be factor.
strat_var	optional factor for stratification.
adjmethod	method for adjusting p values (see p.adjust)
distr	Computation of p-values, see coin::wilcox_test.
plevel	threshold for significance.
symbols	predefined as b,c, d...; provides footnotes to mark group differences, e.g. b means different from group 2.
sep	text between statistics and range or other elements.

Value

A list with matrix of adjusted p-values and character vector with significance indicators.

Examples

pairwise_wilcox_test(dep_var = mtcars$wt, indep_var = mtcars$cyl)
