int2x2: Interaction 2x2 table

Description

Estimates the interactions from an 2x2 table under the null hypotheses of independence.

Usage

int2x2(x, margin = 3, pTabMethod = c("dirichlet", "half", "classical"))

Arguments

x

a 2x2 table

margin

if multidimensional table (larger than 2-dimensional), then the margin determines on which dimension the independene tables should be estimated.

pTabMethod

to estimate the propability table. Default is ‘dirichlet’. Other available methods: ‘classical’ that is function prop.table() from package base or method “half” that add 1/2 to each cell to avoid zero problems.

Value

The independence table(s) with either relative or absolute frequencies.
