File-Backed Matrix Class with Convenient Read and Write Access
Description
Interface for working with large matrices stored in files,
not in computer memory. Supports multiple non-character
data types (double, integer, logical and raw) of
various sizes (e.g. 8 and 4 byte real values).
Access to parts of the matrix is done by indexing,
exactly as with usual R matrices.
Supports very large matrices.
Tested on multi-terabyte matrices.
Allows for more than 2^32 rows or columns.
Allows for quick addition of extra columns to a filematrix.
Cross-platform as the package has R code only.
