A class interfacing FILEVECTOR C++ library 
for storage of and fast consecutive access to 
large data matrices in out-of-RAM disk mode 
with regulated cache size. Columns of matrix 
are accessible very quickly.

classes

a package providing interface to C++ FILEVECTOR library
        facilitating analysis of large (giga- to tera-bytes) matrices;
        matrix storage is organized in a way that either columns or
        rows are quickly accessible; primarily aimed to support
        genome-wide association analyzes e.g. using GenABEL and
        ProbABEL

databel_base_R-class function

Objects can be created by calls of the form <code>new("databel_base_R", filename, cachesizeMb)</code>.
FILEVECTOR data are stored using files of form BASE.fvi (index) and BASE.fvd (data). 
"filename" is the BASE name.
