R: Interaction 2x2 table

int2x2 {robCompositions} | R Documentation

## 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.
