| CsparseMatrix-class {Matrix} | R Documentation |
The "CsparseMatrix" class is the virtual class of
all sparse matrices coded in sorted compressed column-oriented form.
Since it is a virtual class, no objects may be created from it. See
showClass("CsparseMatrix") for its subclasses.
i:"integer" of length nnzero
(number of non-zero elements). These are the row numbers for
each non-zero element in the matrix.p:"integer" of pointers, one
for each column, to the initial (zero-based) index of elements in
the column.factors, Dim, Dimnames:sparseMatrix-class.
