This package defines a
ReferenceClass which adds safety and convenience features to the
filebacked.big.matrix class from the
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 file-system-based permissions system. Utilities are provided for using
BigMatrix-derived classes as
assayData matrices within the
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.
