resampling_test: Test the difference between x and y using resampling.

In const-ae/proDD: Identifying Differentially Abundant Proteins from Label-Free Mass Spectrometry Data

Description

The method is an alternative to mean(outer(x, y, `<`)) which doesn't allocate memory and is thus much faster.

Usage

resampling_test(x, y, alternative = c("two.sided", "less", "greater"),
  mu = 0, nmax = length(x) * length(y))

Arguments

x	first numeric vector
y	second numeric vector
alternative	how are x and y compared. Same principles as t.test
mu	test if there is at least distance mu between x and y. Equivalent to calling resampling_test(x, y + mu)
nmax	the maximum number of comparisons. Can be used if the full precision is not needed. Defaults to making all possible comparisons

Value

the p-value, ie. the fraction of elements in x that are smaller than y.
