In dimensio: Multivariate Data Analysis

Complete Disjunctive Table

Description

Computes the complete disjunctive table of a factor table.

Usage

cdt(object, ...)

## S4 method for signature 'matrix'
cdt(object, exclude = NULL, abbrev = TRUE)

## S4 method for signature 'data.frame'
cdt(object, exclude = NULL, abbrev = TRUE)

Arguments

object	A data.frame.
...	Currently not used.
exclude	A vector of values to be excluded when forming the set of levels (see factor()). If NULL (the default), will make NA an extra level.
abbrev	A logical scalar: should the column names be abbreviated? If FALSE, these are of the form 'factor_level' but if abbrev = TRUE they are just 'level' which will suffice if the factors have distinct levels.

Value

A data.frame.
