  "Description": "Interface for working with large matrices stored in files,\nnot in computer memory. Supports multiple non-character data\ntypes (double, integer, logical and raw) of various sizes (e.g.\n8 and 4 byte real values). Access to parts of the matrix is\ndone by indexing, exactly as with usual R matrices. Supports\nvery large matrices. Tested on multi-terabyte matrices. Allows\nfor more than 2^32 rows or columns. Allows for quick addition\nof extra columns to a filematrix. Cross-platform as the package\nhas R code only.",
