BioConductor HDF5 interface to R

 This package provides an interface between HDF5 and R.
 HDF5's main features are the ability to store and access very large and/or
 complex datasets and a wide variety of metadata on mass storage (disk)
 through a completely portable file format. The rhdf5 package is thus suited
 for the exchange of large and/or complex datasets between R and other
 software package, and for letting R applications work on datasets that are
 larger than the available RAM.
