# show-methods: Display Objects In planor: Generation of Regular Factorial Designs

## Description

Methods to display the design key matrices.

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14``` ```## S4 method for signature 'designkey' show(object) ## S4 method for signature 'keymatrix' show(object) ## S4 method for signature 'keyring' show(object) ## S4 method for signature 'listofdesignkeys' show(object) ## S4 method for signature 'listofkeyrings' show(object) ```

## Arguments

 `object` object of the class

## Details

The slot `pseudo.info` of the objects of class `keymatrix` is invisible.

NULL

## Note

- An R option named `planor.max.print` is set. It is equal to the number of printed rows and columns in the display of planor matrices. Default is 20. You can change its value by using the function `options()` (see `?options`).
- This method is automatically invoked when objects of the class are displayed (see examples).

Classes where this method applies: `designkey`, `keymatrix`, `keyring`, `listofdesignkeys`, `listofkeyrings`
