r-bioc-sparsearray - 1.4.8+dfsg-1 main

The SparseArray package is an infrastructure package that
provides an array-like container for efficient in-memory representation
of multidimensional sparse data in R. The package defines the
SparseArray virtual class and two concrete subclasses: COO_SparseArray
and SVT_SparseArray. Each subclass uses its own internal representation
of the nonzero multidimensional data, the "COO layout" and the "SVT
layout", respectively. SVT_SparseArray objects mimic as much as
possible the behavior of ordinary matrix and array objects in base R.
In particular, they support most of the "standard matrix and array API"
defined in base R and in the matrixStats package from CRAN.
