## Virtual Class "ldenseMatrix" of Dense Logical Matrices

### Description

`ldenseMatrix`

is the virtual class of all dense **l**ogical
(S4) matrices. It extends both `denseMatrix`

and `lMatrix`

directly.

### Slots

`x`

:logical vector containing the entries of the matrix.

`Dim`

, `Dimnames`

:see `Matrix`

.

### Extends

Class `"lMatrix"`

, directly.
Class `"denseMatrix"`

, directly.
Class `"Matrix"`

, by class `"lMatrix"`

.
Class `"Matrix"`

, by class `"denseMatrix"`

.

### Methods

- coerce
`signature(from = "matrix", to = "ldenseMatrix")`

: ...

- coerce
`signature(from = "ldenseMatrix", to = "matrix")`

: ...

- as.vector
`signature(x = "ldenseMatrix", mode = "missing")`

: ...

- which
`signature(x = "ndenseMatrix")`

, semantically
equivalent to base function `which(x, arr.ind)`

;
for details, see the `lMatrix`

class documentation.

### See Also

Class `lgeMatrix`

and the other subclasses.

### Examples

```
showClass("ldenseMatrix")
as(diag(3) > 0, "ldenseMatrix")
```
