houba: Manipulation of (Large) Memory-Mapped Objects (Vectors, Matrices and Arrays)
Manipulate data through memory-mapped files, as vectors, matrices or arrays. Basic arithmetic functions are implemented, but currently no matrix arithmetic. Can write and read descriptor files for compatibility with the 'bigmemory' package.
