R: Off-diagonal Panel Functions for Table Pairs Plot

Pairs plot panel functions for off-diagonal cells {vcd} | R Documentation

## Off-diagonal Panel Functions for Table Pairs Plot

### Description

Off-diagonal panel functions for `pairs.table`.

### Usage

    pairs_strucplot(panel = mosaic,
      type = c("pairwise", "total", "conditional", "joint"),
      legend = FALSE, margins = c(0, 0, 0, 0), labeling = NULL, ...)
    pairs_assoc(...)
    pairs_mosaic(...)
    pairs_sieve(...)

### Arguments

`panel` | function to be used for the plots in each cell, such as `pairs_assoc`, `pairs_mosaic`, and `pairs_sieve`.
`type` | character string specifying the type of independence model visualized in the cells.
`legend` | logical specifying whether a legend should be displayed in the cells or not.
`margins` | margins inside each cell (see `strucplot`).
`labeling` | labeling function or labeling-generating function (see `strucplot`).
`...` | `pairs_mosaic`, `pairs_assoc`, and `pairs_sieve`: parameters passed to `pairs_strucplot`. `pairs_strucplot`: other parameters passed to panel function.

### Details

These functions really just wrap `assoc`, `sieve`, and `mosaic` by basically inhibiting labeling and legend-drawing and setting the margins to 0.

### Value

A function with arguments:

`x` | contingency table.
`i, j` | cell coordinates.
