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)

Value

• A data frame with one row per group/group comparison, with columns
• group1
  First group being compared

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))
