The "lsyMatrix" class is the class of symmetric, dense logical
matrices in non-packed storage and "lspMatrix" is the class of
of these in packed storage. In the packed form, only the upper
triangle or the lower triangle is stored.

Arguments

Objects from the Class

Objects can be created by calls of the form new("lsyMatrix", ...).

Slots

uplo:

Object of class "character". Must be
either "U", for upper triangular, and "L", for lower triangular.

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

Both extend classes "'>ldenseMatrix" and
"'>symmetricMatrix", directly; further, class
"Matrix" and others, indirectly. Use
showClass("lsyMatrix"), e.g., for details.

Methods

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