This package defines a "BigMatrix" ReferenceClass which adds
safety and convenience features to the filebacked.big.matrix class from the
bigmemory package. BigMatrix protects against segfaults by monitoring and
gracefully restoring the connection to on-disk data and it also protects
against accidental data modification with a filesystem-based permissions
system. We provide utilities for using BigMatrix-derived classes as
assayData matrices within the Biobase package's eSet family of classes.
BigMatrix provides some optimizations related to attaching to, and indexing
into, file-backed matrices with dimnames. Additionally, the package
provides a "BigMatrixFactor" class, a file-backed matrix with factor
properties.
