compMatrix-class {Matrix} | R Documentation |
Virtual class of composite matrices; i.e., matrices that can be factorized, typically as a product of simpler matrices.
A virtual Class: No objects may be created from it.
factors
:Object of class "list"
- a list of
factorizations of the matrix. Note that this is typically empty,
i.e., list()
, initially and is updated
automagically whenever a matrix factorization is computed.
Dim

:inherited from the
Matrix
class, see there.
Class "Matrix"
, directly.
signature(x = "compMatrix", value = "list")
: set
the dimnames
to a list
of length 2, see
dimnames<-
. The factors
slot is currently reset to
empty, as the factorization dimnames
would have to be adapted, too.
