Description: Provides a high-level R interface to CoreArray Genomic
        Data Structure (GDS) data files. GDS is portable across
        platforms with hierarchical structure to store multiple
        scalable array-oriented data sets with metadata information. It
        is suited for large-scale datasets, especially for data which
        are much larger than the available random-access memory. The
        gdsfmt package offers the efficient operations specifically
        designed for integers of less than 8 bits, since a diploid
        genotype, like single-nucleotide polymorphism (SNP), usually
        occupies fewer bits than a byte. Data compression and
        decompression are available with relatively efficient random
        access. It is also allowed to read a GDS file in parallel with
        multiple R processes supported by the package parallel.
