%description
Extends sparse matrix and vector classes from the 'Matrix' package by
providing: (a) Methods and operators that work natively on CSR formats
(compressed sparse row, a.k.a. 'RsparseMatrix') such as
slicing/sub-setting, assignment, rbind(), mathematical operators for CSR
and COO such as addition ("+") or sqrt(), and methods such as diag(); (b)
Multi-threaded matrix multiplication and cross-product for many <sparse,
dense> types, including the 'float32' type from 'float'; (c) Coercion
methods between pairs of classes which are not present in 'Matrix', such
as 'dgCMatrix' -> 'ngRMatrix', as well as convenience conversion
functions; (d) Utility functions for sparse matrices such as sorting the
indices or removing zero-valued entries; (e) Fast transposes that work by
outputting in the opposite storage format; (f) Faster replacements for
many 'Matrix' methods for all sparse types, such as slicing and
elementwise multiplication. (g) Convenience functions for sparse objects,
such as 'mapSparse' or a shorter 'show' method.
