Function `booltype`

returns the boolean type of its argument.
There are currently six boolean types, `booltypes`

is an `ordered`

vector with the following ordinal `levels`

- nobool
non-boolean types

`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`

one scalar element of `booltypes`

in case of 'nobool' it carries a name attribute with the data type.

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

later

`booltypes`

, `is.booltype`

, `as.booltype`
