Boolean types

Description

The ordered() factor booltypes ranks the boolean types.

Usage

booltypes

Format

An object of class ordered (inherits from factor) of length 6.

Details

There are currently six boolean types, booltypes is an ordered() vector with the following ordinal levels():

• nobool: non-boolean type

• logical(): for representing any boolean data including NA

• bit(): for representing dense boolean data

• bitwhich(): for representing sparse (skewed) boolean data

• which(): for representing sparse boolean data with few 'TRUE

• ri(): range-indexing, for representing sparse boolean data with a single range of TRUE

booltypes has a names() attribute such that elements can be selected by name.

Note

do not rely on the internal integer codes of these levels, we might add-in hi later
