Class "lgeMatrix" of General Dense Logical Matrices

This is the class of general dense logical matrices.

Slots

x:

Object of class "logical". The logical values that constitute the matrix, stored in column-major order.

Dim,Dimnames:

The dimension (a length-2 "integer") and corresponding names (or NULL), see the Matrix class.

factors:

Object of class "list". A named list of factorizations that have been computed for the matrix.

Extends

Class "ldenseMatrix", directly. Class "lMatrix", by class "ldenseMatrix". Class "denseMatrix", by class "ldenseMatrix". Class "Matrix", by class "ldenseMatrix". Class "Matrix", by class "ldenseMatrix".

Methods

Currently, mainly t() and coercion methods (for as(.)); use, e.g., showMethods(class="lgeMatrix") for details.

See also

Non-general logical dense matrix classes such as ltrMatrix, or lsyMatrix; sparse logical classes such as lgCMatrix.
