dgeMatrix-class {Matrix} | R Documentation |
A general, numeric matrix in the S4 Matrix representation
Objects can be created by calls of the form new("dgeMatrix", ...)
or, more commonly, by coercion from the Matrix
class (see
Matrix-class).
x
:"numeric"
- the numeric
values contained in the matrix, in column-major order.Dim
:"integer"
- the dimensions
of the matrix - must be an integer vector with exactly two
non-negative values.Dimnames
:Matrix
, see Matrix-class
.rcond
:"numeric"
- an estimate
of the reciprocal of the condition number, if it has been computed
at some point.factors
:"list"
- a list
of factorizations of the matrix.
The are group methods (see, e.g., Arith
)
signature(e1 = "dgeMatrix", e2 = "dgeMatrix")
: ... signature(e1 = "dgeMatrix", e2 = "numeric")
: ... signature(e1 = "numeric", e2 = "dgeMatrix")
: ... signature(x = "dgeMatrix")
: ... signature(x = "dgeMatrix", digits = "numeric")
: ...and other matrix methods available:
signature(x = "dgeMatrix", y = "dgeMatrix")
:
Matrix multiplication; dito for several other signature
combinations, see showMethods("%*%", class = "dgeMatrix")
.signature(x = "dgeMatrix", vectors = "logical")
: ... signature(x = "dgeMatrix", vectors = "missing")
: ... signature(x = "dgeMatrix")
: works via
"dpoMatrix"
, see dpoMatrix-class
.signature(from = "dgeMatrix", to = "matrix")
: ... signature(from = "matrix", to = "dgeMatrix")
: ... signature(x = "dgeMatrix", y = "dgeMatrix")
:
dito for several other signatures, use
showMethods("crossprod", class = "dgeMatrix")
, matrix
crossproduct, an efficient version of t(x) %*% y
