# Filematrix: File-Backed Matrix Class with Convenient Read and Write Access

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.
