| dMatrix-class {Matrix} | R Documentation |
The dMatrix class is a virtual class contained by all actual
classes of numeric matrices in the Matrix package. Similarly,
all the actual classes of logical matrices inherit from the
lMatrix class.
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.
