tidy a pairwise hypothesis test

Description

Tidy a pairwise.htest object, containing (adjusted) p-values for multiple pairwise hypothesis tests.

Usage

## S3 method for class 'pairwise.htest'
tidy(x, ...)

Arguments

x

a "pairwise.htest" object

...

extra arguments (not used)

Details

Note that in one-sided tests, the alternative hypothesis of each test can be stated as "group1 is greater/less than group2".

Note also that the columns of group1 and group2 will always be a factor, even if the original input is (e.g.) numeric.

Value

A data frame with one row per group/group comparison, with columns

group1

First group being compared

group2

Second group being compared

p.value

(Adjusted) p-value of comparison

Examples


attach(airquality)
Month <- factor(Month, labels = month.abb[5:9])
ptt <- pairwise.t.test(Ozone, Month)
tidy(ptt)

attach(iris)
ptt2 <- pairwise.t.test(Petal.Length, Species)
tidy(ptt2)

tidy(pairwise.t.test(Petal.Length, Species, alternative = "greater"))
tidy(pairwise.t.test(Petal.Length, Species, alternative = "less"))

tidy(pairwise.wilcox.test(Petal.Length, Species))
