| dgeMatrix-class {Matrix} | R Documentation |
A general numeric dense matrix in the S4 Matrix
representation. dgeMatrix is the “standard”
class for dense numeric matrices in the Matrix package.
Objects can be created by calls of the form new("dgeMatrix", ...)
or, more commonly, by coercion from the Matrix class (see
Matrix) or by Matrix(..).
x:Object of class "numeric" - the numeric
values contained in the matrix, in column-major order.
Dim:Object of class "integer" - the dimensions
of the matrix - must be an integer vector with exactly two
non-negative values.
Dimnames:a list of length two - inherited from class
Matrix.
factors:Object of class "list" - a list
of factorizations of the matrix.
The are group methods (see, e.g., Arith)
