Description

Do a wilcox test on a data.table. More efficient that coin for large numbers, sort the input by outcome to make it faster.

Usage

test.wilcox.dt(data.dt, two.sided = T, tie.correction = NULL, sort.input = F)

Arguments

data.dt	data.table with two-level grouping factor 'condition' and outcome 'outcome”
two.sided	Do a two sided test?
tie.correction	Apply tie correction (slightly slower, but sometimes necessary). If NULL, tie correction will be applied if there are.
sort.input	Sorts the input by reference, this enables faster ranking (i.e. speeds permutation test)

Value

A data.table containing statistics, including z score and theoretical p value (e.g. z.dt$z).
