pairwise.wilcox.exact: Compute Pairwise Wilcoxon Tests

Description

The function computes pairwise Wilcoxon rank sum and signed rank tests using function wilcox.exact of package exactRankTests.

Usage

pairwise.wilcox.exact(x, g, p.adjust.method = "holm", paired = FALSE, ...)

Value

Object of class "pw.htest" containing the following components:

data.name

a character string giving the names of the data.

method

the type of test applied.

null.value

the location parameter mu.

alternative

a character string describing the alternative hypothesis.

conf.level

confidence level of the confidence interval.

results

a data.frame containing the results of function wilcox.exact

Arguments

x

numeric vector.

g

grouping vector or factor

p.adjust.method

method for adjusting p values (see p.adjust). Can be abbreviated.

paired

a logical indicating whether you want a paired test.

...

additional arguments to fun.

Details

The function computes pairwise Wilcoxon rank sum and signed rank tests.

The implementation is in certain aspects analogously to pairwise.wilcox.test. However, a more detailed output is generated.

Examples

set.seed(13)
x <- rnorm(100)
g <- factor(sample(1:4, 100, replace = TRUE))
levels(g) <- c("a", "b", "c", "d")
pairwise.wilcox.exact(x, g)
## in contrast to
pairwise.wilcox.test(x, g)
