| dMatrix-class {Matrix} | R Documentation |
The dMatrix class is a virtual class contained by all actual
classes in the Matrix package.
Common to all matrix object in the package:
Dim:"integer" - the dimensions
of the matrix - must be an integer vector with exactly two
non-negative values.Dimnames:character vector length
equal the corresponding Dim element.
There are (very simplistic) group methods (see, e.g., Arith)
signature(e1 = "dMatrix", e2 = "dMatrix"): ... signature(e1 = "dMatrix", e2 = "numeric"): ... signature(e1 = "numeric", e2 = "dMatrix"): ... signature(x = "dMatrix"): ... signature(x = "dMatrix", digits = "numeric"): ...
dgeMatrix-class, dgCMatrix-class, and
Matrix-class.
