R: Virtual Class "ndenseMatrix" of Dense Logical Matrices

ndenseMatrix-class {Matrix} | R Documentation

## Virtual Class "ndenseMatrix" of Dense Logical Matrices

### Description

`ndenseMatrix` is the virtual class of all dense logical (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 `"nMatrix"`, directly. Class `"denseMatrix"`, directly. Class `"Matrix"`, by class `"nMatrix"`. Class `"Matrix"`, by class `"denseMatrix"`.

### Methods

%*%

  `signature(x = "nsparseMatrix", y = "ndenseMatrix")`: ...

%*%

  `signature(x = "ndenseMatrix", y = "nsparseMatrix")`: ...

coerce

  `signature(from = "matrix", to = "ndenseMatrix")`: ...

coerce

  `signature(from = "ndenseMatrix", to = "matrix")`: ...

crossprod

  `signature(x = "nsparseMatrix", y = "ndenseMatrix")`: ...

crossprod

  `signature(x = "ndenseMatrix", y = "nsparseMatrix")`: ...

as.vector

  `signature(x = "ndenseMatrix", mode = "missing")`: ...

diag

  `signature(x = "ndenseMatrix")`: extracts the diagonal as for all matrices, see the generic `diag()`.

which

  `signature(x = "ndenseMatrix")`, semantically equivalent to base function `which(x, arr.ind)`; for details, see the `lMatrix` class documentation.

### See Also

Class `ngeMatrix` and the other subclasses.

### Examples

    showClass("ndenseMatrix")

    as(diag(3) > 0, "ndenseMatrix")# -> "nge"
