fromMatrix

toMatrix

The functions <code>fromMatrix</code> and <code>toMatrix</code> help in storing
(and retrieving) matrices using a TileDB backend. In particular they help
for matrices with explicit rownames.

The modern database 'TileDB' introduces a powerful on-disk
format for storing and accessing any complex data based on multi-dimensional
arrays. It supports dense and sparse arrays, dataframes and key-values stores,
cloud storage ('S3', 'GCS', 'Azure'), chunked arrays, multiple compression,
encryption and checksum filters, uses a fully multi-threaded implementation,
supports parallel I/O, data versioning ('time travel'), metadata and groups.
It is implemented as an embeddable cross-platform C++ library with APIs from
several languages, and integrations. This package provides the R support.
